My company recently purchased a license for the Radar chart and I am trying to define specific colors for the lines in the radar chart. We need to compare multiple cars to each other and each car needs to have a specific color on the chart. However, so far I've found no setting to do that. When I define colors under setting "Data Colors" they do not "stick". As soon as we select different cars to compare to each other the line colors change. Example:


Car 22 changed from blue to black. It should remain blue at all times.
I tried conditional formatting, but that only affects the points on the lines, not the lines themselves.
I do see I can activate "Enable Theme" under "Data Colors" but I am not sure what that does. I assume it just activates default theme colors? If so, than that's still dynamic by default.
Is there any other option to change line colors?
Is there any other option?
