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.
