In addition, you can preview the final graph in this dialog.

Note:
  • The recalculate option in this dialog is set to Auto by default.
  • The grouping range will be sorted with default alphabetical order. If this is not acceptable , select the worksheet column, right Click and Set as Categorical. Then, you can modify list order on the Categories tab.
  • By default, we divide the columns into subsets by the first group column when we create a group column plot in this dialog. You can change the default properties of subset in the (Plot Details) Spacing Tab.


Template

GBOX.OPTU (installed to the Origin EXE folder)

Notes

  • Within each grouping, data points are plotted against row index. This will produce noticeably variable tick spacing on the horizontal axis, if there are significant differences in sample sizes among categories. In such cases, the user may find the Grouped Box Chart - Indexed Data, to be a better solution. Once the Grouped Box is created, open Plot Details, go to the Box tab and set Type to Data.
  • If there is more than one grouping range (datasets in the Group Column(s) box), the X axis tick labels will, by default, display as tables. You can control this behavior and formatting of the tick label table, by opening the Table tab in the Tick Labels tab of the Axis dialog.
  • You can modify the spacing between columns or column groups using controls on the Spacing tab of Plot Details as well.
