8.5.2.1.9 The Breaks Tab

Breaks 2 01.png

Starting with Origin 2017, you can use the Layer list to switch between layers in a multi-layer graph.

Breaks

Note: Axis breaks cannot be used when Tick Label Table is enabled.

Enable

Select this check box to show axis Breaks.

Break Half Length

Specify axis break half-length.

<auto> sets axis break half-length equal to distance between major ticks.

Number of Breaks

Set the number of special ticks shown in the axis from 1 to 7. Selecting a number of the breaks, creates a corresponding number Break# pages under the Breaks section.

Display Box for Breaks

The current breaks setting will be displayed in this display box. There are four columns in this display box and each is used for different purpose.

Break From

Specify starting scale value of the range in the axis break.

Break To

Specify ending scale value of the range in the axis break.

Auto Position

Specify whether to determine the position of the break on the axis automatically. If you want to customize the break position, clear this check box and then specify a value in the Position column.

Origin supports two mechanisms to auto position the break:

  • For Origin 2017 and other lower versions, no matter what you entered in the Break From and Break To cell(these values are actual axis range of break), once you checked this Auto Position box, Origin will equally divide the axis length, and then add the breaks at the the dividing points.
    For example, if you want to add 3 breaks at the axis, and select Auto Position, Origin will evenly divide the axis into four parts firstly, and then position the breaks at 25%, 50%, and 75% of axis at length.
  • Since Origin 2018, besides the old behavior above, Origin also supports to use proportional unit for auto break position.
    Once you enter the Break From and Break To values, Origin will subtract the break length and un-auto axis segments from the whole axis length and then rescale the rest segments(which have been truncated by axis breaks) by proportion.
    This behavior can be triggered by checking the option Use Proportional Unit for Auto Break Position in the page-level Display tab in the Plot Details dialog.

Position

This cell is editable only when the Auto Position check box is cleared.

Determines the position of the break on the axis. This value is in units of % of axis length. For example, typing 50 in this text box creates an axis break at the mid-point of the axis. If necessary, Origin will alter the scale on either side of the break to accommodate the specified position.

Buttons

There are two buttons under the display box:

Delete This button is available when one or more break entries are selected in the display box.. It deletes the selected breaks. Note that for multiple selection, you can hold Ctrl key and click on the special tick entries one by one.
Details... This button is used to open the Break Details dialog for further customization of the breaks.

Break Details dialog

This dialog can be opened by clicking the Details... button in the Breaks tab of Axis dialog. It is used to customize the breaks settings.

Scale After Break tab

This tab is used to customize the scale after the break.

Breaks 2 2.png

Break From Specify starting scale value of the range in the axis break.
Break To Specify ending scale value of the range in the axis break.
Position (% of Axis Length) The control is equal to the Auto Position and Position cells in the Breaks tab.

This box is editable only when the following Auto check box is unchecked.

Determines the position of the break on the axis. This value is in units of % of axis length. For example, typing 50 in this text box creates an axis break at the mid-point of the axis. If necessary, Origin will alter the scale on either side of the break to accommodate the specified position.

Auto Scale When the Auto Scale check box is selected, the scale after the break follows settings on the Scale page. This check box is selected by default.
Scale Type

Specify the scale type after the break (as documented in the table for Type in this page). Available only when the Auto check box (see above) is cleared.

Major Ticks

Specify the type, value and the first tick of the major ticks (as documented in the section for Major Ticks in this page). Available only when the Auto check box (see above) is cleared.

Minor Ticks

Specify the type of the minor ticks (as documented in the section for Minor Ticks in this page). Available only when the Auto check box (see above) is cleared.

Tick Labels After Break tab

This tab is used to customize the (Bottom/ Top/ Left/ Right) axis tick labels after the break.


Breaks 2 3.png

Auto When the Auto check box is selected, the tick labels after the break follows settings on the Tick Labels page. This check box is selected by default.
Type

Specify the tick label type after the break (as documented in the table for Type in this page). This drop-down list is available only when the Auto check box (see above) is cleared.

Display /
Dataset Name

Determines how the tick labels are displayed. The drop-down list options depend upon the selection from the Type drop-down list. Available only when the Auto check box (see above) is cleared.

(For options descriptions, refer to Display / Dataset Name on this page).

Minor Tick Labels Available only when the Auto check box (see above) is cleared.
  • Hide
Minor tick labels are hidden by default.
  • Show in each Minor Tick
Select this option to show labels on minor ticks.
  • Show at Specified Indices Only
Show the specified minor tick labels. When you select this option, a Tick Indices text box displays. In this text box, enter space-separated numbers indexed to minor ticks (e.g. "1 4" means to label at 1st and 4th minor ticks between adjacent major tick labels).
