Legend colour mismatch

[#1]

Hi. I'm very new to QV (v11.2) and I have a baffling problem.

I have a line chart where I have used an expression to set the colour of one of the lines ("Overall")  to black (I have used the expression =if(Resolver_Group_Name='Overall',black()) to set the Background colour). This expression has successfully updated the line color in the Legend but the colour of the corresponding line in the chart has remained its old colour, green. So what I've ended up with is a colour in the Legend (black) that doesn't match the colour of the line shown in the Line Chart (green).

Does anyone know how to fix this please? I'm totally stumped.

Can you post sample app

Thank you for helping. Do you mean by QVW file? If so, I can't because it contains sensitive customer data that I am not able to share.

Can you provide sample dummy data and your expressions

Setting back ground color works for me. Check this qvw

Unfortunately, I'm using Personal Edition too and so I can't open your QVW. I think you're telling me that you couldn't replicate the problem though. Thank you for trying to help me!

I think this is a bug due to some format changes in the chart object. Try to create a new chart object (without too much experimenting in styles/colors/sizes) and I guess it should work

Thanks Daniel, I'll have a play.
