Summary

In Origin, a grouped box chart can be created from either indexed data or raw data. The indexed data is arranged as one data column and one or more group columns, while the raw data is arranged as multiple data columns grouped according to the column label row(s).

Once a grouped box plot has been created there are many options to customize the box plots and the axes. The customization options are the same for grouped box plots created from raw data as well as those created using indexed data.

Steps

Create Grouped Box Plot from Indexed Data

1. Select Help: Learning Center menu or press F11 key to open Learning Center. Select Graph Sample tab and then select Box Charts from the "Category" drop-down list.

2. In the workbook Book10, the data in the CC.MI-Index worksheet is indexed data. Column E is the data column and columns C and D can be used as grouping columns. Highlight column E and select Plot > Categorical : Grouped Box Charts - Indexed Data to open the plot_gboxindexed dialog.
3. In this dialog, click the trianlge button at the top of Group Column(s) box to select columns C and D.

Customization by Plot Details Dialog

1. Activate the graph window created from the indexed data. Select and delete the legend object.
2. Select Format:Plot to open the Plot Details dialog. To customize Symbol style, select the Outlies tab and set the following:

In the dialog that opens, you can define a custom color by entering the HSL values (Hue=0, Sat=240, Lum=180). OK to close the dialog. Follow the same procedure for the second color in the Increment Editor dialog with the settings Hue=160, Sat=240, Lum=164. OK out of the Increment Editor:

   

7. In regard to the Box Color, select the first two colors of current color list to the ones we just defined at the previous step, and then select By One for Increment cell and Within Subgroup for Subgroup cell:

   

8. Click OK to apply all the previous settings and close the Plot Details dialog. Click on a box, and in the popup mini toolbar, click the Smaller Gap button thrice to reduce the gap between subgroups.

   

   Finally, the graph should resemble the image below:

   

Customization by Axis Dialog

Continue with the graph from the previous section.
