11 GraphingGraphing
Creating a Graph
Graphs can be created from both hard data and from mathematical functions. With Origin, you can create over 100 graph types using Origin's builtin graph templates. Each of these graphs has been specifically chosen for its applications in various technical fields.
All graph types are accessible from the Plot menu. Note that while most graph types also have a corresponding 2D Graphs or 3D and Contour Graphs toolbar button, some do not. Until you've had time to familiarize yourself with available toolbar buttons, the Plot menu should be your "go to" place for creating graphs.
Creating most graphs involves just two steps.
 Select your data.
 Select the plot type.
Some Origin graph types have very specific data requirements. Other graphs can be created from multiple data arrangements. See the Origin Graph Types section for specific requirements.
Creating Graphs from Worksheet Data
Graphs, Creating
Origin's most generic graph types  line, column/bar, pie  plus a lot of the more specialized types, are created from worksheet data. The following quick tutorial demonstrates importing an ASCII data file and creating a simple graph.

Tutorial: One click to create graph with selected data
 Open a new workbook and select Data: Import from File: Single ASCII... from the main menu.
 Choose the file Samples/Curve Fitting/Multiple Gaussians.dat and click Open.
 Now highlight columns B(Y), C(Y), D(Y) and E(Y) by clicking and dragging across the four column headings.
 Click Plot > Basic 2D: Line & Symbol: Line & Symbol. A graph window is created with four line and symbol plots. Note that the plots differ by line color and by symbol type.
 Return to the worksheet, and again select columns B(Y), C(Y), D(Y) and E(Y).
 This time, select the Plot > MultiPanel/Axis: 4 Panel menu item. Note that a very different plot is created using the same datasets.

We were able to quickly create two different graphs using the same data. The chapter Customizing Graphs discusses customizing graphs and saving templates in more depth.
We are also able to create 3D plot types from worksheet data. The following tutorial demonstrates creating a 3D surface plot, then overlaying it with a 3D scatter plot.

Tutorial: 3D Surface Plot from XYZ Data
 Create a new, empty workbook window and import the file \Samples\Matrix Conversion and Gridding\XYZ Random Gaussian.dat.
 Highlight column C and right click. Select Set As: Z from the flyout menu.
 Select Plot > 3D: 3D Colormap Surface to create a 3D Colormap Surface plot.
 Select the Graph: Layer Contents... menu item or right click the layer icon on the lefttop of the graph to open the Layer Contents dialog. In this dialog, click on dropdown next to the button and select 3D Scatter/Trajectory/Vector from the flyout menu.
 Select column C from the left panel and click on the Add Plot button to add the 3D scatter plot to the graph. Click OK to close the dialog.
 Doubleclick on the plot to open the Plot Details dialog. In the left panel, expand the Layer1 node and then expand the 2nd node which represents the scatter plot. Click and select the branch named Original. Be sure to leave the nodelevel check box selected, otherwise this plot will be hidden.
 In the Symbol tab on the right side, set Shape to Ball, Size to 12 and Color to Color Mapping: Col(C).
 In the Drop Lines tab, clear the Parallel to Z Axis check box.
 Select Layer1 from the left panel of the Plot Details dialog. In the Lighting tab, under Mode, select Directional. Click OK to close the dialog.
 Click on the scatter plot in the graph to select this plot, then in the Style toolbar, click on the button and select the Rainbow palette.
Your graph should look like this:
:

 You can hold down the R key on your keyboard and use the mouse to freely rotate the 3D surface. With the pointer tool active, click on the layer for additional controls to move, stretch and rotate the surface.

Worksheet Column Plot Designations
Worksheet Plot DesignationsColumn Plot DesignationsPlot Designation
The labels (X), (Y), (Z), etc. in column headings are referred to as the Column Plot Designation. Columns can also be designated as Label, Disregard, Y Error or X Error. Each plot type has certain data requirements (e.g. a simple line plot requires one X and one Y dataset) and column plot designations work in concert with settings saved in the graph template, to allow you to quickly create a graph.
To set the Column Plot Designation, select a column or multiple columns, then from the menu choose Column: Set as:<option>; or rightclick and choose an option from the Set As: context menu.
In the 1st tutorial above, we plotted 2D graphs, which require Y data from one or more worksheet columns. The Y data were automatically plotted against the X column data to their left. In 2nd tutorial, we plotted a 3D graph using Z data. The Z data were plotted against X and Y data columns to the left of the Z data column.
Selecting Worksheet Data
Selecting Data, WorksheetRange, Worksheet DataData RangeSelecting Data, for PlottingGraphing Worksheet DataPlotting Worksheet Data
Various ways to select data for plotting:
 Single column: Click on the column heading, e.g. B(Y)
 Multiple columns: To select a small number of contiguous columns, click on the first column heading and drag the pointer to the last column heading. To select a large number of contiguous columns, click on the first column heading, use the scroll bar at the bottom of the worksheet to locate the last column, then press the SHIFT key and click on the last column heading. To select noncontiguous columns, press the CTRL key while clicking on the desired column heading.
 A range in a column: Click on the first cell of the range and drag to the last cell of the range.
 Multiple ranges within a column: Select one range. Press the CTRL key while selecting each range. When plotting, each range will be treated as a separate data plot in a plot group.
 Ranges across multiple columns: If cells are contiguous, click on the first cell and drag to the last cell. If cells are not contiguous, press the CTRL key while selecting each range. Each range selection will be treated as a separate data plot in a plot group.
 Range(s) across all columns: Click on the first row heading and drag to the last row heading, to select multiple rows. This will select data in all columns in the worksheet. Press the CTRL key while selecting row headings for noncontiguous rows. Each range selection will be treated as a separate data plot in a plot group.
 Entire worksheet: Press CTRL+A to select the entire worksheet; or mouse over the bottomright corner of the blank cell in the upperleft corner of the worksheet. When the pointer becomes a downwardpointing arrow, click to select the entire worksheet.
 Specific columns: To select columns by data in column label rows (header rows); or to select columns using a pattern, choose Edit: Select.
Creating a Graph from Matrix Data
Plotting Matrix DataGraphing Matrix Data
As discussed in the Matrix Book, Matrix Sheets and Matrix Objects chapter, a matrix is a dataset of Z values arranged as an array of columns and rows which are linearly mapped to X (column) and Y (row) values. Matrix data is used to create 3D, contour and heatmap graphs  all of which require require "3D" data. In earlier versions of Origin you had to have your data in a matrix to create such plot types but this is no longer the case (see discussion of the Virtual Matrix below). A few graph types such as a colorfilled surface with error bars still require matrix data.
There are still many situations in which you will be creating 3D plots from matrix data. If data are stored in a worksheet and for one reason or another, you need to convert it into a matrix form, see Converting Worksheets to Matrixes.
Once your data are in a matrix form, plotting matrix data is simple: activate the matrix window then select your plot type using a Plot menu command or corresponding 3D and Contour Graphs toolbar button. Since you cannot plot only a portion of the matrix, data selection isn't necessary. You can, however, choose a subset of the data plot to display once the graph is created. See Editing Plot Range in the Manipulating Data Plots section of this chapter.
The Virtual Matrix
The Virtual Matrix concept was covered in the Matrix Book, Matrix Sheet and Matrix Object chapter of this Guide. To recap, a virtual matrix is a block of worksheet cells which contain Z values, with X and Y coordinates in the first row or column label row, and first column. X and Y coordinates don't have to be evenly spaced and can even contain text or date/time data. Graphing Virtual Matrix DataPlotting Virtual Matrix Data
When selecting and plotting virtual matrix data to 3D, Contour and Heatmap graph types, the worksheet's Column Plot Designations are ignored. Instead, a dialog box is opened where you designate your X and Y coordinates. The intersecting data points are then treated as Z values.

Tutorial: Contour Plot from Virtual Matrix
 With a new workbook active, use the Data: Import from File: Import Wizard... menu to open the Import Wizard dialog.
 Press the browse button in the dialog and select the file Waterfall.dat from the Samples\Graphing subfolder.
 This file has an import filter already associated with it. Press the Finish button to import the file.
 With the workbook active, press CTRL+A to select the entire sheet.
 Now select the Plot > Contour: Contour  Color Fill menu item. The plotvm dialog will open.
 In the dialog, set the Y Values in dropdown to Column Label, and then set the Column Label dropdown to Excitation Wavelength(nm).
 Set the X Values in dropdown to 1st column in selection, then press OK to close this dialog.
 The contour plot will be created.
 Use the Graph: Speed Mode... menu item, then in the dialog that opens, set the Speed Mode dropdown to Off and press OK. This will turn off speed mode so that all data points are plotted (see the discussion of Speed Mode, below).
 Click on the contour plot to select this data plot, then from the Style toolbar, click the Palette button and then select the Pumpkin Patch palette. Your graph should look similar to the image below:

 Once you customize your contour levels and colors, you can save your settings as a Theme, or simply copypaste your customizations from one graph to another. To save a Theme, rightclick on the graph and choose Save Format as Theme; or use the Colormap Theme controls on the Colormap/Contours tab of the Plot Details dialog box.

2D and 3D Function Plots
Graphs, Function
Plotting FunctionsGraphing, Functions
Function Plots, 2D and 3D
Parametric Function Plots, 2D and 3D
To create function plots and parametric function plots, select File: New: Function Plot menu. There are four options to choose from:
Type

Function Form

2D Function Plot

y = f(x)

2D Parametric Function Plot

x = f1(t) y = f2(t)

3D Function Plot

z = f(x, y)

3D Parametric Function Plot

x = f1(u, v) y = f2(u, v) z = f3(u, v)

These plot types are also accessible from the function plot buttons on the Standard toolbar.

Tutorial: 3D Function and 3D Parametric Function in Same Layer
 From the menu, choose File: New: Function Plot: 3D Parametric Function Plot...
 In the dialog that opens, click on the arrow button at the top right side of the dialog, and from the flyout menu select the builtin example Partial Torus (System) and press OK to close the dialog. The function plot will be created.
 With the function plot window active, invoke the menu File: New: Function Plot: 3D Function Plot....
 In the dialog that opens, enter 5 and 5 for the From and To edit boxes for x and y scale.
 In the Z(x,y) edit box, enter 0.
 Set the dropdown at the bottom left corner of the dialog to Add to Active Graph and press OK to close dialog.
 The Z=0 plane will be added to the graph, and the plane will properly intersect the parametric surface plot. You can hold down the R key and use the mouse to freely rotate the plot.

 Some function plot dialogs provide sample formulas. Click the arrow button beside Theme at the top of the dialog box to access them. You can download more examples at http://originlab.com/3dfunctions.
 For 2D parametric, 3D, and 3D parametric function plots, data is generated when the function plot is created. To create data for 2D function plots, rightclick the plot and choose Make dataset copy of Function or if on the Function tab in Plot Details, click the Workbook button.
 Besides function plots, you can also create graphs with all builtin and userdefined nonlinear curvefitting or surfacefitting functions. From the menu, choose Analysis: Fitting: Simulate Curve... or Simulate Surface.... You can even add noise to the plot. Corresponding data is created as well.
Plotting without Using Column Plot Designations
Column Plot DesignationsPlot DesignationWorksheet Plot Designations
While Column Plot Designations remain an important concept, they are no longer required by many Origin graphing and analysis operations. For instance, the Plot Setup dialog box allows you to freely specify which column is used as X, Y, etc. when plotting, thereby overriding the Column Plot Designations.
In order to make full use of the Plot Setup dialog box, you need to have some familiarity with the hierarchy of objects contained in the Origin graph window.
Graph Page
Graph Layer
Graph Layer Frame
Layers, Graph
Page, Graph
Pages, Layers, Plots and the Active Plot
Graph PageGraph LayerActive LayerLayer Icon, Graph
Each Origin graph window is comprised of a single, editable graph page. The graph page is defined by the white area inside the graph window. Anything that lies outside the page is not printed or exported. By default, the dimensions of the graph page are defined by the printable area of your default printer driver; without adjusting settings, a printed graph should fill the printed page.
 The graph page must contain at least one, and may contain as many as 1024, graph layers.
 Each graph layer generally contains one or more data plots (graphical depictions of datasets). Note that the graph in the image above contains three graph layers, represented by the three nonprinting layer icons in the upperleft corner of the graph page. Note that there is one layer icon which is highlighted, indicating that this is the active layer.
 Just as there is only one active layer, there is only one active plot in a graph. Usually, the active plot is the first plot in the active layer. To verify which plot is active, click on the Data menu while the graph is active. The active plot will have a check mark beside it.
The hierarchical structure of the graph page can be seen in these places:
 The Plot Details Dialog Box (Format: Page ...)Plot Details Dialog Box

 Reordering data plots in a layer or moving data plots to another layer.
To create a graph with the Plot Setup dialog, make sure no data is selected in the active worksheet and choose the plot type that you want to create (from the Plot menu or by clicking on a toolbar button).
To open the Plot Setup dialog for an existing graph window, rightclick on any layer icon in the upper left corner of the graph window and select Plot Setup..., or choose menu Graph: Plot Setup....

Tutorial: Creating a Simple Line Plot with the Plot Setup Dialog Box
 Click the New Workbook button on the Standard toolbar.
 Click Data: Import From File: Single ASCII, browse to the Origin installation folder and import the file \Samples\Curve Fitting\Step01.dat. Starting from column B, columns are actually paired  X data and Y data  but by default all columns are assigned a "Y" Column Plot Designation on import.
 Without selecting any data, click Plot > Basic 2D: Line. This opens the Plot Setup dialog box.
 Click the two "doublearrow" buttons to show all three dialog box panels.
 In the middle panel, select the "X" box for Column B (Sensor Ax) and the "Y" box for Column C (Sensor Ay), then click the Add button to add the plot to Layer 1 in the bottom panel.
 Select the "X" box for column D (Sensor Bx) and the "Y" box for Column E (Sensor By), then click Add.
 Select the "X" box for column F (Sensor Cx) and the "Y" box for Column G (Sensor Cy), then click Add. Three plots are added to Layer 1.
 Press CTRL and click on each plot in the bottom panel to select all three, then rightclick and choose Group.
 Click OK to create a grouped line plot.


Tutorial: Creating a Graph with Data from Multiple Worksheets
 Click the New Workbook button on the Standard toolbar.
 Click Data: Import From File: Multiple ASCII, browse to the Origin installation folder and select Sensor01.dat, Sensor02.dat and Sensor03.dat under \Samples\Curve Fitting\ to import. After Import, 3 workbooks are created.
 Without selecting any data, click Plot > Basic 2D: Line+Symbol. This opens the Plot Setup dialog box.
 Expand the top panel if it is hidden. From the Available Data list, choose Worksheets in Folder.
 Select Sensor01, Sensor02 and Sensor03 sheets in the top panel.
 In the middle panel, select the "X" box for Column A (Displacement) and the "Y" box for Column B (Sensor Output), then click the Add button.
 Click OK to create a grouped Line+Symbol plot using Sensor Output columns from 3 worksheets.

 The Plot Setup middle panel only allows choosing one X column at a time.
 If your worksheet is set up with the correct Column Plot Designations (e.g. XYXY) but you only want columns with same Long Name, click the toggle in the upperright corner of middle panel so that only plottable columns show (e.g. for 2D plot types, X columns are not shown). Then you can sort the columns and select all columns with same Long Name and plot them together. The Y columns will be plotted against corresponding X columns.
 To change a data plot's type, choose the corresponding plot in bottom panel. Corresponding X and Y columns will show in middle panel. Choose a new plot type in middle panel and click the Replace button.
 All data plots in a group share the same plot type. If you want to change the plot type of a single plot in a group, rightclick the Group node in bottom panel and Ungroup first.
 Drag and drop data plots in the bottom panel to move them to different layers.
 If the bottom panel is hidden and you have selected columns in the middle panel, you can directly click the OK button to create your graph.
Manipulating Data Plots
The following sections discuss higher level modifications to existing graphs such as changing plot type, adding or removing plots from the layer and controlling the density of plotted points (Speed Mode). For more detailed plot customizations, including those involving such things as changing plot symbols, colors, and legend customizations, see the Customizing Graphs chapter.
 The following methods of manipulating data plots in the graph window are fairly easy to use. Thus, you may want to choose File: Open Template and pick your template to create a blank graph window. Then, using the methods below you can add and group data plots in the graph.

Changing Plot Type
Plot Type, ChangingPlots, Exchanging
Some Origin plot types (e.g. scatter, line, line+symbol) allow you to interchange the plot type of an existing plot with a few other select plot types. Some examples:
 Scatter, line, line+symbol, column/bar are interchangeable.
 3D scatter/trajectory/vector, 3D bars, 3D surface are interchangeable.
To change the plot type of an existing plot:
 Rightclick on the data plot and choose Change Plot to: Graph Type from the shortcut menu.
 Click on the data plot and choose Format: Plot... and in Plot Details choose from the Plot Type dropdown list.
 Click on the data plot, then click one of the supported graph toolbar buttons.
Note that if you switch plot types and the selected plot is part of a plot group, all plots in the group are switched.
 A word of caution: This is an old Origin feature, and for a quick change of plot types in a singlelayer graph it works well. Changing plot types in a multipanel, multilayer graph can lead to unwanted outcomes. When working with more complex graphs, it is better to create a graph directly using the specified Plot menu command or toolbar button .

Exchanging Data Plots
Plots, Adding/Removing/HidingPlot DesignationWorksheet Plot DesignationsColumn Plot Designations
You can quickly change the data source (X, Y, or worksheet) of a plot using these context menu commands. Rightclick on a data plot, then select one of these options:
 Change X. This menu item allows you to change the assignment of X data to another data column in the same worksheet.
 Change Y. This menu item allows you to change the assignment of Y data to another data column in the same worksheet.
 Change Worksheet. This menu item allows you to replace both X and Y with data from another worksheet. The selected worksheet should have the same Short Names, the same Column Plot Designations and the same row index range as the current worksheet.
 If you have a grouped data plot, then clicking once on any of the plots in the group will select the entire group. Click a second time to select a particular member of the group. The context menu options to change worksheet, X, or Y are available only when a single data plot is selected.


Tutorial: Changing X and Y assignment of a data plot
 Start with a new workbook and import the file automobile.dat from the Samples\Statistics subfolder of the Origin installation folder.
 Select the Gas Mileage column and select the Plot: Basic 2D: Scatter menu item. The Gas Mileage column is plotted against the default X column Year.
 Rightclick on the data plot and select Change X: Engine Displacement. The Gas Mileage column is now plotted against Engine Displacement.

Note: If new data is significantly outside of the current range for X or Y axes, you will be asked if the graph should be rescaled. If data are not significantly different, you may want to manually rescale the graph (Hot key: CTRL+R).

 If you perform analysis on the data plot (e.g. linear regression with Recalculate set to Auto), the fit results will automatically update when you change X/Y or the worksheet.

Adding, Removing and Hiding Data Plots
Graphs, Adding or Removing Plots
Use the following methods to add or remove data plots from a graph.
Adding Data by Drag and Drop
Graphs, Add Data by Drag and DropDrag and Drop Plotting
You can add data to a graph by drag and drop. When using this method, Origin relies on worksheet Column Plot Designations to create the plot.
 Select the worksheet data (one or more columns or a range of one or more columns).
 Move the mouse over the left or right edge of the selected range.
 When the pointer looks like this , hold down the left mouse button and drag the data to the graph window. Release the mouse.
 If there are multiple layers in the graph, drag the data to the desired layer, then release the mouse.
 Usually the current plot type is used when plotting by draganddrop. To change the global plot type to use when drag and drop, choose Preferences: Options... from the main menu. Go to the Graph tab and change the Drag and drop plot type.

Adding and Removing Data with the Layer Contents Dialog Box
Graphs, Layer Contents Dialog Box Layer Contents Dialog Box
Open the Layer Contents dialog box by doubleclicking or rightclicking on the layer icon(s) in the top left corner of the graph page. Controls in the left panel can be used to filter and list available datasets. The right panel lists datasets that are plotted in the active layer.
Controls in the center of the dialog box allow you to add or remove plots from the active graph layer. When adding data to the graph, click the list button (downwardpointing arrow) to preselect the plot type before adding data to the layer. Use controls in the right panel to group or ungroup plots, or reorder plots in the layer.
Adding, Removing, Replacing or Hiding Data Plots with the Plot Setup Dialog Box
Plots, Adding/Removing/HidingPlot Setup Dialog Box
Among other things, the Plot Setup dialog box can be used to add or remove data plots from the graph.
 To add plots to the graph, use the top panel of Plot Setup to identify your source data.
 Use the controls in the middle panel to specify the plot type and how the data selection should be treated (as X, Y, yError or Label).
 In the bottom panel, choose the Layer to which you want to add plots, then click the Add button.
 To remove a plot from the layer, select the plot in the bottom panel, then rightclick and choose Remove.
 To hide a plot, uncheck the Show check box for the plot.
 To replace a plot, select the plot in bottom panel, then change the X and Y selection and plot type in middle panel and click the Replace button.
Adding Data by Direct ASCII Import
Graphs, Direct ASCII ImportASCII Data, Import to Graph
You can import ASCII files directly into the active graph window using the the Import ASCII toolbar button. Note that this method works only with files having a simple structure and it supports only the simplest of graph types  Line, Scatter, Line + Symbol, Column and Bar charts.
 Click the Import ASCII button. This opens the Import ASCII dialog box.
 Choose a file.
 Click Open.
The file is imported and plotted in the active graph window.
Adding Data by Copying and Pasting a Plot
You can copy a plot from an existing graph window and paste it into the same or another window.
 Click on the plot to select it and press CTRL+C.
 Click on the target graph and press CTRL+V.
Simultaneously, a ClipbN worksheet is created. You can open this worksheet by doubleclicking on the plot, then clicking the Workbook button at the bottom of Plot Details; or rightclick on the plot in the graph window or in the Object Manager and choose Create worksheet ClipbN.
 You can also "copy" a plot and paste the data to a worksheet. Click on the plot to select and press CTRL + C, then click on a cell and press CTRL+V to fill the column with plot data.

Removing or Hiding Plots with the Object Manager
Object Manager
The Object Manager is a dockable panel that allows for easy manipulation of graph layers and data plots. See the section on The Object Manager in this Guide.
To hide or remove plots, rightclick on a plot and choose from the shortcut menu:
 Show or hide plots of the same Long Name.
 Show all plots.
 Remove a plot from the graph window (hidden plots can be quickly shown again; removed plots must be added back using one of the above methods).
 If the plot is part of a group, you can rightclick on an individual plot and remove just that plot or you can rightclick on the group icon and remove the entire plot group.
 When you rightclick on a plot, you can use Hide Plots with Same Name and Hide All Plots shortcut menu items to quickly hide selected plots in the window without removing them entirely (restore plots by enabling their display in the Object Manager or in Plot Details).
Removing or Hiding Data with Plot Details
In the left panel of the Plot Details dialog box (Format: Plot...), rightclick on a plot and choose Remove or Hide from the context menu. Remove will delete the data plot from the graph so if you just want to temporarily hide a plot, choose Hide. Neither of them will delete data from worksheet or matrix.
Deleting Plots using the Delete Key
Click on a data plot (either in the graph window or Object Manager) and press the Delete key. If the selected plot is part of a group, the entire group is deleted.
Note that this is more sweeping than the Remove shortcut menu command in that it will remove an entire plot group from the graph window. This action does not delete worksheet or matrix data.
To restore the deleted plots, choose Edit: Undo Remove Plot from the main menu.
Editing Plot Range
Once a graph is made, you can edit the plot display range, specifying only a portion of the plotted data:
 Rightclick on the plot and choose the Edit Range... shortcut menu command. Edit the From and To values.
 In the right panel of the Layer Contents dialog box (Graph: Layer Contents), turn on the Range column by rightclicking on the column headings and choosing Range. Click on a plot's range values, then click the ... button that appears to the right side of that column.
 In the bottom panel of Plot Setup (Graph: Plot Setup), click on the plot range in the Range column and click the ... button that appears to the right side of that column.
 Choose Graph: Rescale to Show All to rescale the graph after editing the plot range.

Grouping Data Plots
Graphs, Grouping PlotsGrouping Plots
When you make multiple range or column selections, then create a graph, Origin groups the resulting data plots in the graph layer. This applies to most 1D (statistical) and 2D graphs, plus 3D XYY (XYY 3D bar, 3D ribbon, 3D wall, and 3D waterfall plots) and 3D XYZ (3D scatter, 3D bar) graphs.
Grouping provides for quick creation of presentationready graphs because each plot in the group is assigned a differentiating set of plot attributes (line color = black, red, green...; symbol shape = square, circle, triangle...; etc.). Assignments are made by cycling through a predetermined (usermodifiable) increment list of styles. For instance, the first plot of a grouped line plots might be denoted by a black line; the second plot might be denoted by a red line (the second color in the color list), the third plot by a green line (the third color in the color list), and so on.

Tutorial: Grouping (or ungrouping) plots manually
 Via the Layer Contents dialog boxLayer Contents Dialog Box
 To open the Layer Contents dialog box, doubleclick on the layer n icon in upperleft corner of the graph window.
 To create a group, select the desired data sets from the Layer Contents list (use CTRL + select, SHIFT + select, or simply drag the mouse to select multiple data sets).
 Click Group. Note that each plot in Layer Contents is now preceded by a gn (for "group1", "group2", etc.).
 To ungroup, click on one of the grouped data plots in the Layer Contents list and click Ungroup.
 Via the Plot Setup dialog boxPlot Setup Dialog Box
 To open the Plot Setup dialog box, ALT + doubleclick on the layer n icon in upperleft corner of the graph window.
 To create a group, select the desired plots from the Plot List (use the CTRL or SHIFT keys to select multiple data sets).
 Rightclick and select Group. Note that a Group icon now precedes the selected plots in the Plot List.
 To ungroup, rightclick on the Group icon and choose Ungroup from the shortcut menu.

Speed Mode
Graphs, Speed Mode Speed ModeData Reduction, Graphs
With Speed Mode, you can control the number of data points displayed in a graph layer. This option is most used when working with large data sets, though note that there have been improvements in this area and Origin now has Density Dots and Color Dots graph templates specifically for creating scatter plots of large datasets.
Speed Mode can be turned on for any 2D or 3D graph. When Speed Mode is enabled, the layer icon displays in red and a Speed Mode is On watermark appears in the layer. The watermark is not included when printing, copying, or exporting the graph.
To adjust Speed Mode settings:
 With your graph active, select Format: Layer... from the Origin menu.
 Select the Display/Speed tab.
 For plots created from worksheet data, Select the Worksheet Data, Maximum Points Per Curve check box to enable Speed Mode for all the data plots in the layer that are created from worksheet data. Type the desired value (n) in the associated text box. If the number of data points in a data plot exceeds n, Origin displays a subset of the data plot containing n points, drawn by extracting values at regular intervals from the data set.
 For 3D data plots created from a matrix or for contour data in the layer, Select the Matrix Data, Maximum Points Per Dimension check box to enable Speed Mode. Type the desired value (n, m) in the X and Y text boxes. If the number of data points in a data plot exceeds n or m, Origin displays a subset of the data plot composed of  at maximum  n by m points. This subset is drawn by extracting values at regular intervals from the matrix columns (X) and rows (Y).
For broad control, you can select Speed Mode from the Graph menu. This opens the speedmode XFunctiondialog. The dialog lets you specify which windows the settings should apply to ( Target ) and also, offers several levels of data plot thinning from Off to High, plus Custom.
 Click the Enable/Disable Speed Mode button on the Graph toolbar, to toggle Speed Mode on/off for all layers in the graph window.

To turn off the Speed Mode is On watermark:
 Select Preferences: Options to open the Options dialog box.
 Select the Graph tab and clear the Speed Mode Show Watermark check box and refresh the graph, if needed. Note that this only disables the watermark; it does not disable Speed Mode.
Notes on Speed Mode:
 There are a couple of changes to Origin 2020 that involve Speed Mode. Skip Points and Speed Mode now plot the last data point, by default (controlled by system variable @SMEP). Secondly, drawing speeds are now faster with Speed Mode off, especially when using square scatter symbols + colormapping (in which case it is 5 to 10 times faster). 
 The Speed Mode controls on the Display/Speed tab of the layer's Plot Details only apply to what you see on screen. They do not apply to graphs that are printed or exported, by default.
 If you wish to skip points in printouts, use controls in the Print dialog. See the discussion of the Skip Points feature as it applies to some graph windows in the Origin Help file.
 If you wish to apply Speed Mode settings to graphic export, please see this discussion of Performance Group controls on the Miscellaneous tab of the Plot Details dialog box or use controls under the Export Settings node in the Graph Export dialog.
 Speed Mode settings are saved with the graph template. If you make changes to Speed Mode settings for a particular graph type, you will have to resave the graph template to make those changes permanent.
 Always exercise judgement when using Speed Mode. Since Speed Mode systematically weeds out a portion of your data points, any graph in which Speed Mode is turned on, may  or may not  accurately represent your data, to your satisfaction. Always familiarize yourself with your data and adjust and compare Speed Mode settings to ensure that trends in your data are accurately depicted.

Origin supports over 100 plot types. Origin's 2D graphs are plotted from Worksheet data. Origin's 3D graph are plotted from Worksheet data (XYY, XYZ), a worksheet arrangement we refer to as a Virtual Matrix or from Matrix data.
 Origin Graph Samples of most 2D and 3D graph types are included with your Origin software. To view graphs, supporting data and guidelines for making the graphs, choose Help: Origin Central; or click on the Origin workspace to activate Origin and press F11 on your keyboard.

The tables below list all Origin graph types, grouped by Plot menu category:

 The Plot menu icon for each graph type precedes the graph name.
 The Notes column provides basic information on data requirements. For more specific data requirements, click on the graph name beside the Plot menu icon.

 Origin 2020 adds a number of new plot types including Sankey Diagrams, Alluvial Plots, Kite Diagrams and Doughnut Charts. Additionally, there is an updated and more powerful Pie Chart; variations include "Pie of Pie" (portion of a pie is charted as a second pie), "Bar of Pie" (portion charted as bar) and "Doughnut of Pie" (portion charted as doughnut) and a variable radius Pie ("Pie with Different Radius"). Origin 2020 also includes an updated and more flexible Dendrogram for plots of multivariate data.
