What You Will Learn

This tutorial will show you how to:

  • create a stacked column plot with error bars.
  • enable an axis break without a gap.
  • divide one axis into several segments and set scales separately.

Steps to Add Axis Break with No Gap

  1. Select Help: Learning Center menu or press F11 key to open Learning Center. Select Graph Sample tab and then select Column and Bar Charts from the "Category" drop-down list. Double-click on the graph sample below to open the sample "Column and Bar Charts - Zero Length Break to Change Axis Scale".

    Note: This tutorial is associated with the folder Custom Axis Scale to Show Different Scale of the "Tutorial Data" project:<Origin EXE Folder>\Samples\Tutorial Data.opju.
  2. Activate the workbook "Temperature & Exothermic Energy". select all the columns in sheet 1 and choose Plot > Basic 2D :Stacked Column to create a stacked column plot with error bars.

  3. Positive columns cannot be seen since their absolute values are too small comparing to those of negative columns.
  4. We can break the Y axis at Y=0 and use different axis scale for those two segments. First double click on the Y axis to open the Axis dialog and set Y Range (in Vertical icon) to be from -180000 to 80

  5. Then go to the Breaks tab with Vertical icon active, and enable 1 axis break. Also set the Break Half Length to 0 so the break indicator will not show. Set both the Break From and the Break To to 0 so the axis will break at 0 and no break gap shows. Uncheck Auto Postion and enter 50 for the Position cell.

More Customization Steps

The following steps can further customize the graph to be exactly the same as the image in Summary.

  1. Set the X scale to be from -2 to 20, Major tick by increment 2.
  2. Go to the Grids tab and select both Vertical and Horizontal icons, select the Opposite check box so the grid lines opposite to both X and Y axes will show.
