Origin 2018 Features

Origin Interface



Graph Samples tab is restructured and allow selecting a specific Plot Type category as well as keyword searching.


Images in worksheet cells now be viewed as enlarged popups when running mouse over the cell.

For example, when mousing over the following cells, an enlarged popup image will be displayed.

  • Sparklines cell.
  • A cell with Embedded graph.
  • A cell with Inserted Image from File.

A System Variable @CET is used to control the behavior:

@CET=0, use default size of 250x250
@CET=1 to 29, disable this feature
@CET > 30 is user defined size in pixel, scaled by DPI scale factor


Access to the Character Map in Worksheet cell edit mode.

Double click a cell to enter the edit mode.

Ctr+M or right-click and choose Character Map to insert symbol into cell using the font specified for the cell.

The benefit of this is that it allows actual Unicode characters to be inserted into Label rows, rather than codes used in previous versions of Origin. Hence, then the values in Label Rows are displayed elsewhere, those Unicode characters will be used.


Insert non-keyboard Unicode characters similar to MS Word and other apps using 4-digit code and Alt+X keyboard combination.

To insert a character that is not supported by your keyboard, find the relevant 4-digit Unicode code via Google. Then, when in edit mode, type in the 4 digits and hit Alt+X to convert it to the actual character. Note: If the font for the location does not support the relevant character, it may not display properly even though the character is valid.

This feature works in:

  • Worksheet cells even if rich text isn't enabled.
  • Axis titles, legend, and any regular text label on a graph.
  • Many Origin dialogs that support text entry such as those related to axis title, legend, and text objects. Also dialog like the Find in Projects and others.
  • Notes window.


File: Export: As PDF File...menu added for worksheet

In Origin 2018, File: Export: As PDF File... menu is added.

In previous versions of Origin, Export worksheet as PDF file is an option in File: Export: As Image File... dialog. But is not obvious.


Export Graph...menu shows under File: Export: if there is graph floating or embedded on active sheet. for example:.

  • Result sheet with embedded graph.
  • Regular sheet with embedded graph.
  • Regular sheet with floating graph.
  • Graph sheet.

Origin 2018, if there is embedded graph in workbook, Export Graph... menu shows under File: Export:

In previous versions of Origin, the user needs to double-click on a floating or embedded graph prior to exporting it. 

ORG-15820Remove the "Yes-No" confirmation dialog about saving changes to "Tools: Options" modifications.

After you make modifications in the Options dialog (accessible from menu Tools: Options) and click "OK" button, the changes will be saved directly WITHOUT the dialog to confirm.


App Central Dialog.

The new App Center dialog (keyboard shortcut F10) centralizes App discovery, installation, without having to leave Origin  and open a web browser (unless you choose to learn more about selected Apps).


Context menu to Hide Color List/Palettes and Show All to restore

Some of the color lists or color palettes may not apply to user. Then user can right click from the color list or palette list to hide it.

Chose Show All to make hidden ones visible again.

This also works for user-defined color list/palettes.


Tooltip Improvements on Color related toolbars
  • When mousing over a single color block, HEX number and (R, G, B) show


New Graph Types




Bridge Chart/McKinsey-style waterfall.

Support Bridge chart with total and connecting lines.

  • Coloring bars based on Increase/Decrease and Total.
  • Set Data Indices for Total/Subtotal in Plot Detail: Bridge Chart tab.
  • Show Connect Line and Connect by Subset in Plot Detail: Bridge Chart tab.
  • Select a point in Bridge Chart, right click and you can select Set as Total/Subtotal. After select it, it will append data index to Data Indecies for Total/Subtotal in Plot Detail.
  • New Plot button group in Plot Main Menu: Bridge Chart, Stacked Bridge Chart, Stacked Total Bridge Chart, Horizontal Bridge Chart


Double Y Box Chart.

Plot: Box Chart: Double Y Box Chart menu is added.

In Origin 2018 because on Miscellaneous tab of Plot Details dialog → Graph level, Column/Bar/Box Gap Across layers is checked.

The checkbox used to work for column/bar plot only.

Note: This checkbox is only enabled if

  • layers are all linked.
  • For each linked layer, on Link Axes Scales tab, X Axis Link is straight 1:1.
  • For each linked layer, on Size/Speed tab of each linked layer, Unit is % of the linked layer


Plot multiple line plots with colors mapped to a palette. Corresponding color scale shows in legend.

It was doable before Origin 2018 but needs a lot of steps.

  • Plot: Multi-Y: ColorMap Line menu is added in Origin 2018 to quickly plot it.
  • Easy to change palette.

Labels, Legend, Color Scale and Bubble Scale



GUI to Customize Symbols in Legend.
  • Manually create a symbol+line legend entry with many customization options.


 Customization symbol on left side of legend box. 

  • Dumbell style line+symbol legend.
  • Scaling factor of symbol size, line thickness to be different from plot symbol size and line thickness.
  • Adjust the left part (legend symbol block) width and height.


Simplify Categorical Values Legend Dialog.

The "Combine Elements Indexed by Same Column" checkbox is hidden and on so such elements will always show as combined in Legend.

To bring back the old dialog, set system variable @LCC=1 and reopen the dialog.


Better Hint and Examples in Update Legend dialog.

ORG-16899Symbol like legend for customized single point in line plot and line+symbol plot.

Before Origin 2018, if user customized a single point in line graph, the symbol failed show in legend.

If user customized a single point in line+symbol graph, the special point legend showed as line+symbol.

In Origin 2018, both are supported. For line+symbol plot, if you want the single point legend show as line+symbol as before, set @lsl=0.

ORG-16486Use One Legend Type Only and Auto UpdateAdd a new menu option named Use One Legend Type Only and Auto Updateunder Legend context menu. When it's checked and select one type of legend in Legend context menu, all other types of entry will be deleted. When data point/data plot is added or deleted, the legend will be updated automatically.


Support leader line for Pie chart label.

Show a leader line between pie slices and labels.


Support Label for 2D Vector Plot.

Double click vector plot to go to Label tab of Plot Details dialog to add labels.

  • Label can customized to be from any column in same sheet with customization.
  • Label can be rotated and be positioned to arrow head, tail with offset, etc.


Control Decimal Separator for Labels & Annotations at Graph Page Level.

This is useful if graph is being submitted to multiple journals some of which want different separators.

Note: Graph may have to be refreshed after changing the setting to see the changes.

In the past, this is a global control in Tools: Options dialog so user can not set different graph windows differently.


Improvement to data labeling at specified Indices only.

In addition to manually entering specific indices, now specific columns may be selected that contain indices for the specific labels.

Plot Manipulation



Use System Increment list when adding new plots into existing graph.

Origin 2017 supported customizing system color list, shape list, etc. for line, line+symbol, scatter plot.

But when user added more then 1 column of data to existing graph, the customized system color list wasn't used. Instead the color list defined in graph template was used. 

In Origin 2018, when adding more than 1 column of data to existing graph, the customized system color list will be used. 


Easier way to turn on and off active dataset indicator (red frame) in Legend via:

  • Legend Context menu.
  • Update Legend... dialog.

The red frame around plot part of legend is the activate dataset indicator. Analysis, etc. tools always work on active dataset by default. So it's useful to see it sometimes.

The control to turn it on or off is hidden on Legends/Titles tab of Plot Details dialog in the past and hard to find.

Keep Scale in mode untill pressing ESC.

User wants to Scale In toolbar button and keep on zooming in by drawing a rectangle.

Before 2018, after scale in once, need to click Scale In button again to zoom in further.


CInteractively pick data points from graph.

Interactively pick points and collect them in a workbook.

Mouse over the plot you want to pick point. A tooltip will show about the plot's X,Y info. Right click and click Pick  Data Points...

Click a point in graph and make sure it's the point you want to pick. Then press Enter or double click to confirm the selection. Continue it till done. A workbook will be created with x,y coordinates and row indexing, etc. 

ORG-17055Make new Layer Content dialog easy to useReorder the column order in left panel of Layer Contents dialog so Column Short Name with Plot designation can be more obvious. In Origin 2018, the default display order in left panel is: Short Name, Long Name, Book, Sheet.


Column Gap control for Double Y Column Plot.

For Double Y column plot, user can go to 1st plot's Spacing tab to set Overlap as a negative value to show some gaps between the the columns.

There is no such control in Origin 2017 and earlier so the bars are always connected in the past.


Show Total Label on Stacked Column/Bar.

Show total value on stacked column/bar or 100% stacked column/bar.

  • Check on the checkbox on Stack tab of Layer level in Plot Details dialog
  • Go to Label tab of plot level in Plot Details to customize diplay, such as decimal place, etc.


Symbol size increments for each plot in group.
  1. Specify the size increment by start size and increment step 5(6), or manually enter each plot's size.
  2. Read symbol size from column label row, e.g. a user-defined parameter row:Size


Use Cluster tool to easily change part of plot to a different color.

Cluster Gadget is improved so user can easily select a range of plot and color it.

User can use cluster gadget to create group for the region of interest and check Color Data by Category.

Then the region will be colored red.

Open Plot Details, user can go to Color List tab to change color.


Graph Theme support for Anti-Aliasing.

Before Origin 2018, there was Enable/Disable Anti-Aliasing toolbar button orpage.aa=1 property for user but it was tedious for user to do it for each graph.

A built-in graph theme AntiAliasing.oth is added on Graph tab of Tools: ThemeOrganizer.

User can apply it to existing graphs or set it as system theme for future graph creation.


Plot 2 Y columns with numeric X, columns will be plotted against row indexing by default.

If plotting one Y column as Columns/Bars with numeric X, it will be plotted as X value positions.

If plotting multiple Y column as Columns/Bars with numeric X, it will be plotted with row indexing by default. Use system variable @DRX>0 (default is 16) to enable this feature only if dataset size is smaller then this value. Set @DRX=0 to disable this change completely. 

ORG-15295Improve Preview for patterns and filled colors

Hover mouse over a pattern block, the preview of this pattern will show.

ORG-16257Allow drag-and-drop to add dataset into the group of Stacked ColumnIn 9.4, it is not possible to adding a dataset into a Stacked Column by drag-and-drop. Now you can add new dataset into the group of Stacked Column/Bar plot by drag-and-drop.

Graph Page and Layer



Distribute selected layers/graphic objects horizontally or vertically.

Two buttons are added in Object Editor toolbar.

Select all graphic objects and click it to keep begin and end positions of the objects and

distribute them evenly in one direction. E.g.

This also works for multiple Layers. User can press Shift key and select multiple Layers. Then click the button to distribute layers horizontally or vertically.

ORG-14777Control display of  masked data at graph page level.

Display of masked data on graph can now be controlled for individual graphs via the following Labtalk:

page.mask = 2; // Display masked data on active graph

page.mask = 1; // Hide masked data on active graph


Ctrl+A Keyboard shortcut Selects All in Graph and Layout window.

This feature is useful when user needs to select all layers in agraph or all objects in layout to move and/or resize together.

  • Ctrl+A to select all layers in a graph.
  • Ctrl+A to select all objects in layo




Support Arrow at axis begin and end in 2D graphs.

Arrow node on Line and Ticks tab of Axis dialog


Add custom reference lines to your graph:

  • Use statistical functions on plotted data, such as mean and standard deviation.
  • Functions can be combined, such as mean+1.5*sd.
  • Use custom equations or expressions to add lines based on axis scale values.
  • Lines are saved in graph template for repeated use.
  • Lines update when data changes.

Define Reference Lines based on statistics or expression and saved in graph template for future use.

  • Statistics


Click Details on Reference Lines tab of Axis dialog to define reference lines.

  • Expression


Change Filling color between Reference Lines with Alternate Fill.

Before Origin 2018, if Alternate Fill was checked for Reference Lines, user couldn't change fill color.

In Origin 2018, click Details... button on the tab. Then select all entries on the left panel and change Fill Color to change all fill colors together.



Show reference line in Trellis plotYou can control reference line show in specific panel in trellis plot through Reference Lines dialog's Show on Panel control. Label will show when open Reference popup to incicate panel index.
ORG-15437Support Reference Line for Polar(and other special plot types)Polar graph, Radar chart and Ternary all support reference line.


Different ways to wrap tick labels.

Wrap based on layer length

Wrap by Minimum number of characters.

E.g. in the following example, set tick label display to Custom Display with MMM dd HH:mm:ss

And to wrap with by minimum 1 char. It will show Month, date and time each on one row.



Axis Break Improvements:

  • Support Anti-Aliasing for Axis Breaks.
  • Use Proportional Unit in Each Segment of Axis Breaks.

In Origin 2018,

  • When Anti-Aliasing toolbar button is pressed, axis break will look smooth as well.
  • Use Proportional Unit for Axis Break Positions checkbox is added on Display tab of Page level of Plot Details dialog.


Support not plotting filtered rows for text axis:

  • By default, if data is filtered, text axis will exclude them as well.
  • To include filtered data position in text axis, run wks.khra=1 in worksheet and then plot.

E.g. Some data are filtered in worksheet.

When plot column plot in Origin 2018, only those data in display will be plotted with their corresponding X axis.

Before Origin 2018, though the filtered data are not plotted, the x axis still kept their position with blank tick label.

Note: This only applies to X column that contains text and not set as categorical.


Allow number of Major axis ticks to be 0.

This will allow user to create a graph with only begin and end ticks and no ticks in between by:

  • On Scale tab, Set Major tick by Count and Number of Ticks to be 0.
  • On Special Ticks tab, choose Show in Show column of Axis Begin and Axis End.


No extra space after / or - when using /<U> and -<U> as axis unit.

Before Origin 2017, In Tools: Options →Axis tab, when specifying unit separator as /<U>, or -<U>, an extra space shows after / or -.

In Origin 2018, by default no space will be added after / or -. User can manually set it as / <U>, or - <U> to add a space.

We will continue to have space before units separators by default. System variable @ATSS is added to control space before unit separator.

1: space before unit separator (default)
0: no space before unit separator


Axis end doesn't look nice when zoomed in

Before Origin 2018, when zoomed in, Axis ends didn't look good.

In Origin 2018, the Axis ends will look nice even when zoomed in, depending on different coordinate system.

-2 (default): square for Cartesian (=90 degree) coordinate, round for other coordinates (!=90)
-1: follow @LCA
0/1/2 round/square/flat, 

3D and Contour



3D XYZ Colormap Surface supports colormapping from another column.

In the past, we don't support this so user has to convert XYZ data and the coloring data into Matrix first since 3d colormapping surface plotted from matrix supports colormapping from another matrix object.

ORG-16167S23D XYZ Colormap Surface supports custom boundary.

Contouring Info tab is added in Plot Details dialog to specify XY boundary.


Support no smoothing when set custom boundary for XYZ contour.

In Origin 2018, user can uncheck Smoothing checkbox when using Custom Boundary.

Before Origin 2018, the checkbox couldn't be unchecked so there was always some smoothing effect. Workaround: Set system variable @tcs=0 to minimize the number of smoothing data points


Support Lighting effect for 3D walls plot.

Before Origin 2018, Lighting was only supported for 3D OpenGL based surface and 3d Bars.

In Origin 2018, we added the support for 3D Walls.


Drag on graph to move light source.

Hotkey S is added on 3D graph to move light source.

  • S key + arrow keys
  • S key + drag
  • S key with + to zoom in. S key with - to zoom out




Fitting: Add more Fit Statistics to fitting Result Table Quantities.

In previous versions, some Fit Statistics were excluded from list of available Quantities in Table. More items are available in Origin 2018.

ORG-13544Fitting: Null hypothesis footnote is added under ANOVA table of Nonlinear Curve Fit, Multiple Regression, and Polynomial Fit report sheets.Requested by customer.
ORG-16969Fitting: FDF should include Category

Add new Category key to FDF General Information section.

  1. When D&D the FDF to Origin, FDF is automatically installed under the Categorys according to the Key.
  2. If this new key is empty or missing, it will pop up dialog to ask about which category to install.
  3. Operations in Fitting Function Builder and Fitting Function Organizer will update this Category key, such as Create/Move func.
  4. Fitting Function Builder allow to change category since 2018.
ORG-15062Fitting: Fit until converged supports all datasets for multiple data

In Nonlinear Fit tools, add All option in the Select data to iterate drop-down list which allow to iterate on multi datasets at the same time. 

ORG-13999Fitting: Put all weighting methods in dropdown items for all input datasets
  • In Nonlinear Fit tools, Data Selection page, all weighting methods are putted in the Weights drop-down list whichi allow to set multi datasets' weight mehod.
  • In Nonlinear Fit tools, Data Selection page, add Apply Weight to All menu to Range's context menu list. 
ORG-14528Fitting: Smarter Handling of NLFit X Data TypeWhen Iteration Algorithm is set as "Levenberg Marquardt" in Nonlinear Fit tools, Fitted Curves page, default X Data Type is changed as new method: Follow Curve Shape. (Note: except the Nonlinear surface/matrix fit tool)


Peak Analysis: Automatically set Area/Amplitude boundaries based on Peak Finding Direction.
  • If Peak Finding direction is Positive only, then Area boundary is >=0.
  • If Peak Finding direction is Negative only, then Area boundary is <=0.
  • If If Peak Finding direction is Both, then no boundary is set.


Statistics: Add grouping support for Statistics on Rows.

Statistics on Rows now allows grouping based on values in a columns label row. For example, in below illustration, results will be grouped by values in the Long Name label row.

ORG-16534Statistics: Discrete Frequency for categorical data needs to add zeros for if not found

Discrete Frequency dialog  adds a checkbox Show Zero Count Categories.

ORG-15908and ORG-7392Statistics: Improve Weibull Fit with RRX method and Add Plot for survival function and hazard function for weibull fit - Origin Pro

Weibull Fit dialog adds below new items:

ORG-15020Statistics: Weibull Fit Calculate 100% Probability Which Can't PlotOrigin 2018 changed Weibull Fit tool's Score Methods from Kaplan-Meier to Benard, which also affects Distribution Fit tool's probability plot .
ORG-13424Statistics: Rename Weibull Percentiles into percentages

Weibull Fit tool's PlotData worksheet column label changed.

ORG-8382Statistics: Add ellipse coefficient to correlation matrix

From Origin 2018, the major and minor radius of the correlation ellipse in Scatter Matrix are exported to the result sheet. No matter you create the Scatter Matrix from Plot: 2D: Scatter Matrix or Statistics: Descriptive Statistics: Correlation Coefficient, you can find the major and minor radius of each correlation ellipse by A and B values in the Parameters column label row of the PlotData worksheet, where A is the major radius and B is the minor radius.

ORG-14788and ORG-14789  Statistics: Add Median Absolute Deviation, Robust Coefficient of Variationand Harmonic Mean for Statistics on Columns/Rows tool

Statistics on Columns/Rows dialog adds below checkboxes:

ORG-11294Statistics: Add option of Exclude cumulative counts plot to Pareto chart dialog

Add options to the Pareto Chart (Binned and Raw) dialog

  1. Add Show Cumulative Percent Plot checkbox to plot the cumulative counts plot.
  2. Add branch Combine Smaller Counts in One Category to group combine smaller values settings.


General: Set Default Digits for individual types of analyses.

Prior to Origin 2018, there is only global control of display digits via Digits in Report in the Numeric Format tab of Tools: Options.

In 2018, users can specify default Default Digits to apply for different types of analyses. For example:

After an analysis is done, right click in the table in the result sheet and choose Digits...  Set the Digits values and check Save as Default.

The default will apply to other instances of that particular analysis operation in the future.

To reset back to system default: Close Origin. Go to User Files folder and delete Defaults.XML.


General: Ignore Hidden column/plots when choosing all columns or plots for analysis.

A system variable, @AIP, is added to control whether ignore hidden column(s)/plot(s) or not when adding all as input(s) for analysis.

  • =1 (default), ignore hidden plots.
  • =0, include hidden plots.

For example, if some columns or plots on a graph are hidden, when opening an analysis dialog that supports multiple inputs and the user chooses All Colu

Data Processing




Worksheet Cell Formula.

The Expression in cell should start with =

For Example:

  • =total(A1:F1) – total of 1st rows from A column to F column.
  • =max(A)*A2 – maximum value in column A divided by 2nd cell. of A.
  • =A1$+B1$ – concatenate text in A1 and B1.

This is supported in data area and user-defined column label rows.


Keep formula exactly as entered by user.

Before Origin 2018, formula auto expanded in some cases.

  • Sheet index in formula auto expanded to sheet name. E.g. user typed 1!A. It auto expanded to Sheet1!A.
  • If type A+0.5 in column A formula, it will become This+0.

System variable @SCVU is added in Origin 2018.  By default what you type will be what you see. If you want it to go back to 2017 behavior, set @scvu=0.


New X-Function wcellfmt added to set selected cells' format.

Run wcellfmt -h to see Help and examples.

E.g. the following example first uses wxt x-function to select all rows with B>0

Then set the fill color of the selected cells to green

ORG-16790Copy Full Precision change to text only

Since Origin 2018, when use choose Copy Full Precision, the copied content will be text only in clipboard, then it would be convenient for user to paste to another application.

Set @CPF = 0 to go back to 2017 behavior.


Rename sheet name and long name inNavigate Worksheetdialog.

For a workbook with many sheets, user can right click any sheet tab and choose Navigate to delete, order, duplicate sheet etc. But renaming sheet wasn't supported.

Added in Origin 2018 now.


System Variable to hide worksheet tab tooltip.

When mousing over a worksheet tab, worksheet short name, long name and comments show. But it can block other sheets.

A system variable @WTT is added. Default is 1 (enabled). Set it to 0 to disable worksheet tooltip.


Increase the Maximum number of Sheets per workbook.
  • Before Origin 2018, the maximum sheets per book was 255. Now in Origin 2018, it's 1024.
  • page.nlayers property is set to writable so run page.nlayers=1024 to quickly create 1024 sheets. It's faster than using repeat 1023 { newsheet; }.
  • If there are more than 255 sheets in a book, the project can't be saved as opj. Can only be saved as opju.


Increase the Maximum Undo times to 100.

In Origin 2018, the default maximum number of Undos is set to 100. Before Origin 2018, it was 10 times. Corresponding system variable: @UN.

ORG-16162Support carrying over column categories in worksheet query.Support carrying over column categories during worksheet query data extraction to new book/sheet.
ORG-16223Better color syntaxing for LabTalk function and Spreadsheet column name notation in Set Column Value dialog.In Set Column Value dialog, use Navy color for LT variable, Wine color for LT function, Pink color for Spreadsheet column name.




Support Undo for Import ASCII, CSV, and Excel.After importing either ASCII, CSV, or Excel, user can choose Undo from the Edit menu or Ctrl+Z to undo the import.


To make Reimport and Clone Import more obvious, a new Import toolbar is created with more buttons.

  • One click to reimport if the data file is changed outside.
  • Reimport with Dialog button to open import dialog again to change some settings.
  • Clone Import to import more data based on current book/sheet with analysis/graph.


Set Origin to be the default software to open data files.

In Origin 2018, if user right-clicks on a data file and set the file to open with Origin or set Origin to be the default program to open it,

data file will be imported into Origin directly whenever such a file is double-clicked.


Display imported file name in a new worksheet label row entitled "SourceFile".

A new checkbox "Add Filename User Parameter Row" in Import dialogs.

If checked, "SourceFile" label row appears in worksheet after import. This label row can be used in any place label rows can be used such as legends.


Importing specified columns and rows in ASCII, CSV, and Excel dialogs using specific syntax.

The most important thing is to understand about the syntax is the meaning of five symbols ",", ":", "~", "|" and "-".

E.g. using column as an example:

  1. 1,3,6 – Only import column 1, 3, 6. 
  2. 1:10,20:0  – Two ranges are imported, from column 1 to 10, and then from 20 to the end. The user can add more ranges with delimiter ",".
  3. 1:10|3-2  – Import columns from 1 to 10, but read 3 columns and skip 2 columns. So column 1,2,3,6,7,8 are imported.
  4. 1:10,~3:7 – Import columns 1 to 10, but exclude columns 3 to 7. So column 1,2,8,9,10 are imported.
  5. 1,3:5,10:20|1-2,~16 – Import column 1, then columns 3 to 5. Then import columns 10 to 20 reading 1 column and skipping 2 columns and also exclude column 16. So column 1,3,4,5,10,13,19 are imported.

Under Partial Import node. See ASCII Import dialog for example syntax.

  • If Custom isn't checked, use From, To, Read, Skip buttons to construct the partial import.
  • If Custom is checked, user can import specified columns/row by following our syntax. Sample example hint is given. 


More options in Excel Import.
  1. More sheet renaming options: This is useful if user import sheets in different files and wants to rename sheet with Excel file name.
  2. Put Filename or Sheetname to Comments, SourceFile, or SourceSheet column label rows.


Support Skip Column when importing CSVfile.

This was already supported in some other import like ASCII, Excel, etc.

Added the Read Columns and Skip Columns in CSV Import.


Copy and Paste Excel cell(s) to Origin Graph will paste as text by default.

Before Origin 2018, if user copied some cell(s) in Excel and then pasted it into Graph window, it was pasted as Excel object by default. User must use Edit: Paste Special... to paste as unformatted text.

In Origin 2018, the cells will be pasted as text by default. If user wants to paste as Excel object, user can choose Edit: Paste Special... or context menu and choose to paste as "Microsoft Excel Worksheet".

Set system variable @PXLTXT=0 to change back to old behavior.


Import ASCII one row header line with special formatChange the Extract Long Name and Units from Same Line node to Composite Header Line No. node, when this node is check, we show the Composite Pattern node for specify the composite pattern of Long Name, Unit andComment, if it is <auto>, it will works as the old way.


Import Excel- Support Importing Sheets into Separate Workbooks Add a new option Start New Books for Each Sheet in "1st File" and "Multi-File" Import Mode, but currently re-import is not supported in this mode.


New impASC on GUI and related changes

Reconstruct the Import ASCII X-Function "impASC"(including the impASC setting dialog), and also it is compatible with the old one in LT script. However, we also add a system variable @IA for users who want to use the old one to roll back.

@IA = 1
File Menu: impASC_94
Tool Bar: impASC_94
LabTalk Script (run -xf impasc): impASC_94
Reimport (from old 94 .ogw): impASC_94
Drag and Drop (with old 94 .oif): impASC_94

@IA = 2
File Menu: impASC
Tool Bar: impASC
LabTalk Script (run -xf impasc): impASC
Reimport (from old 94 .ogw): impASC
Drag and Drop (with old 94 .oif): impASC


Support Partial Row Import for Excel

Suppport Partial Row Import for Excel import tool, add Partiial Rows branch with five nodes under Options: Partial Import:

Exporting and Presentation



Ignore hidden columns in ASCII Export.

Before Origin 2018, when exporting a worksheet as ASCII data, hidden columns were exported.

In Origin, by default hidden columns will be ignored and will not be exported.

To export hidden columns, set system variable @UHC=1. 


Define the region to export or copy page in Origin 2018.

  • Choose Edit:Edit Export Margin Offset...menu or double click on edge of page to open Export Margin Offset dialog.

  3. For File List, select Sensor01, Sensor02, and Sensor03.dat under <Origin EXE folder>\Samples\Curve Fitting\.
  4. Set Result Sheet as Result.
  5. Click OK. In Summary sheet, there is a graph image from the analysis Template on each row. Mouse over it to pop up a larger image of the graph.

How to include a graph image in each row or report sheet:

  1. Open the analysis template .OGWU file. e.g. <Origin EXE folder>\Samples\Batch Processing\Sensor Analysis.ogwu.
  2. Copy an embedded in the report sheet and Paste Link in a cell in the sheet that will be used as Summary Sheet in Batch Processing. 
  3. Save the analysis template and use it in Batch Processing dialog.
ORG-13454Batch processing support XYZ columns, worksheets, and data ranges.

1.XYZ column

support in both using existing xyz datasets or import from files.

2. Use existing worksheets

support using any sheet from opj as input, if selected it will copy all columns to data source in analysis template.this options should be useful for statistics tools not require column designation.

3.Use Existing Ranges

it will have two input range: Fixed Range and Batch Range, Fixed Range means those data which is fixed in each process. this options should be useful for statistics tools.


Improve Labtalk script to support exporting specified embedded graph(s) or graph sheet(s) during batch processing viaScript After Each Process inBatch Processingdialog.
Example scripts:
//To export a graph sheet with sheet name: Graph1

expGraph type:=pdf overwrite:=rename export:=specified page:=Graph1!;
//To export a graph sheet with is the 5th sheet
expGraph type:=pdf overwrite:=rename export:=specified page:=5!;
//To export embedded graph in result sheet by graph short and long name
expGraph type:=pdf overwrite:=rename export:=specified pages:="FitLine - Linear Fit";
//To export embedded graph in FitLinear result sheet by graph short name
expGraph type:=pdf overwrite:=rename export:=specified pages:=FitLine;

//To export embedded graph in worksheet cell
expGraph type:=png filename:="<long name>" export:=specified page:=col(A)[3];

//To export multiple graph cells or floating graph
 expGraph type:=pdf  overwrite:=rename page:=2!; //sheet index

Project and Data Management

ORG-15165New Project File Extension for New File Format and File DialogIn Origin 2018, New File Extensions like OPJU, OGWU, OGGU, OTWU, etc are added to various opening/saving file dialogs drop-down lists.
Convert Origin to use Unicode for text and a new file structure for various Origin files including projects.

File extensions are changed to: OPJU, OGWU, OGGU, OTWU,, etc.

New structure allows file sizes to be reduced (sometimes greatly).

It also allows files to be loaded more quickly.


Support Preview and  thumbnail file images in Windows File Explorer for Origin Files.
(Toggle Windows File Explorer Preview pane using the  Alt+Pkeyboard shortcut). 


If Origin crashes, it will restart with last Autosaved OPJ/OPJU loaded

If an OPJ/OPJU file is opened and being worked on in Origin, it will be autosaved every 12 minutes by default and if Origin crashes, user can go to Autosave folder to find it. 

In Origin 2018, if Origin crashes, it will restart with last Autosaved OPJ/OPJU loaded so user doesn't need to manually find it in Autosave folder. 


  • If it happened that Origin crashes before 1st autosave happened, then the original OPJ/OPJU will be loaded. 
  • If you have worked on a new project file but never saved it. It is called Untitled.opj Origin doesn't autosave Untitled.opj
  • Old feature: User can control how often project is autosaved in Tools: Options dialog.


In the Projects tab, Origin projects that were modified and not actually saved can be reopened with the modifications in place via the Unsaved Files list.

Even if the user chooses not to save a project file (OPJU), an autosaved OPJU will be kept for 7 days by default. If the user actually saves the project after modifying it, the unsaved version will be removed.

  • The unsaved version can be opened from the Unsaved File list in the Projects tab.

  • The user can turn off this feature from Tools: Options: Open/Close tab.

  • The System Variable @USKT is used to control how many days to keep the unsaved OPJU file. Default is 7 (days).
  • The system Variable @USM is used to limit the maximum OPJU size for Autosave Unsaved Project. Default is 20 (MB).




Labtalk: Option to let graph source always plot all Y columns in worksheet.

With graph window active, run layer.group1.AllCols=1; in Script Window.

Then all Y data in the worksheet will be plotted and, as Y columns are added or deleted, they will be removed/added to the graph.

Note: This only applies to worksheet with XYYY... plot designation.


Labtalk: New X-Function wcellfmt added to set format of selected worksheet cells.

Run wcellfmt -h; in Script window to see Help and examples.

For example: The following example first uses wxt x-function to select all rows with B>0 and then set the fill color of the selected cells to green.


Labtalk: Diff() function supports padding in the begin or end of range.

Add optional argument to current function:

vec Diff(vec[,n]) //support length of vector is N

where n can be
0 default, output vector length is N-1
1, pad 0 at the end, output vector length is N
2, pad 0 at the beginning, output vector length is N
3, 1st value in v, diff(v,0), last value in v, output vector length is N+1

For example: Suppose there are 10 rows in column A and Set Column Values of B as

diff(A) – returns 9 numbers. No value in last row.

diff(A,1) – returns 10 numbers. 0 at the end.

diff(A,2) – returns 10 numbers. 0 at the beginning.

diff(A,3) – returns 11 numbers. The begin and ending values are original begin and ending values in A. In between are diff(A) values .


Labtalk: LabTalk Command to convert OriginC C and CPP files to become OCZ for distribution.

Syntax for the conversion command is is

file -ocz password srcpath destination;

srcpath can have wildcard in file name, and in this case destination must be a folder location and destination files will use source file name and extension changed to OCZ.
password must be between 2 to 20 characters and space is now allowed.

The Message Log will list each successful conversion and indicate at the end as "Done!" or "Failed!". If any errors occur, they will be displayed in a Messagebox.

For example:

file -ocz junk "%YOriginC\*.c??" "%Yabc"

file -ocz "aB12#$" "%YOriginc\test.c" "%Yjunk.ocz"

ORG-16492Labtalk: Better LabTalk access to plotting X-functions.

Also, two new LabTalk functions added to get the first point and last point of a plot.


double FirstPoint(vector vec);
double LastPoint(vector vec);

ORG-16451Labtalk: LabTalk Save command updated to support new file format
  • save -i filename; //Save the active worksheet, graph, or matrix window to a file with new file format, file extension will be ogwu, oggu, ogmu 
  • save -ij filename; //Save the active worksheet, graph, or matrix window to a file with old file format, file extension will be ogw, ogg, ogm 
  • save -ik filename; //Save the active workbook as analysis template with the extension of ogwu 
  • save -ikj filename; //Save the active workbook as analysis template with the extension of ogw

  • save -di/-di1 filename; //Save the project as new file format with the extension of opju 
  • save -dij filename; //Save the project as old file format with the extension of opj 

Also, use option X to Save With Format Determined From Supplied File Extension. Following switches are supported, -ix, -tx, -dix.

For example, 

  • save -DIX %yMyProject.opj; //saves the project in the opj format with the name MyProject.opj
  • save -DIX %yMyProject.opju; //saves the project in the opju format with the name MyProject.opju
  • save -DIX %yMyProject; //saves the project in the opju format with the name M
ORG-17258OC: Additional dialog-related Win API functions

OC: Code Builder Should Handle UTF-8 filesNow Code Builder is able to handle UTF-8 files - loading, editing, saving, and debugging.


OC: Origin C compiler Must Handle UTF-8 Source Files

In Origin 2018, we support executing UTF-8 files in Code Builder.

1. All code files (*.c, *.ogs etc.) Origin ships (so it is placed EXE folder) is kept as ANSI.
2. When create a new empty code file, it is also ANSI. However, when saving, we will pop up msg to ask to if save as Unicode when Unicode characters appear.

This file contains characters in Unicode format which will be lost if you save it as an ANSI encoded file.
Click Yes to save as Unicode (UTF-8) encoding format.
Click No to save as ANSI.

ORG-16655HTML: Provide format option to convert variables in OC to string in html
