When exporting a chart in arcpro 3.7 which is a set of histograms created using the split by option, ensure the purple border is not included in the export (to clipboard) as it makes that function useless when including the chart in a report as it retains the purple border.
I think the copy to clipboard is a great feature as it skips the need to export to a file, but is not useful if it retains the purple selection boundary.
A discussion of exactly what I'm talking about is here.
