Chart: dimension bg color when using {1} in expression

[#1]

I'm looking for the best way to set the bg color of a dimension when using a chart with {1} within an expression and selecting, in another object, just one of the dimension values. I attaching a test qvw and its image. Thanks.

You can do as in the attachment ( look at the chart on the right).

Colors are not the same but you can update them.

The way to do it is to create a table containing the colours for each type.

Hope it helps !
