Group values in a bar chart

This chart has categorized the countries into regions with multi-level category labels.

You can create great looking categories by deleting some of the values in the region column. Make sure the region column is sorted and then delete all duplicates. See this picture.

The region names are now centered on the chart. You can find this chart on sheet 2 on the attached file below.
