I am using a Modern Chart on a dark background, the chart has a right angled border line across the top & left of the chart that I cannot remove.
any suggestions on how to get rid of it?
I don't have any charts to test. Did you look at the properties of the control itself? Does it have a transparent border or is it set to something else?
I'm used to Charts in Excel so the general prosperities I don't have an issue with, but the Chart border I cannot fix. I have tried everything I know and it still shows up!!
Normally for a light background you would just set border style to transparent in the column chart properties
However for a dark colour background, I get the same as you.
Looks like a bug. I've just reported it
