I am using a grouped bar chart.
A simplified example is shown here:
The number of entries varies, and often can be large.
This causes the group headings (e.g. “Model1”, “Model2”) to overlap as they are all being displayed horizontally.
The tick labels seem to auto-rotate when there are many entries, but this does not rotate the group titles.
I have tried using ‘tickangle’ and ‘textangle’, but they don’t affect the group titles.
What to do in this case?
