I'm not sure this is possible, but when looking at a chart and I select either "multicolored" or "by dimension" I have the option of 12 colors or 100 colors. I want to be able to customize what those 12 colors are. In the example below you can see that the first 3 colors are different shades of blue, lets say I want to color 1 to red, color 2 to blue and color 3 to green. Is that possible? (The chart type is combo chart)
Thanks for the answers and that is why I stayed away from an expression, the lack of a legend to define it...
I haven't investigated themes so my knowledge here is lacking.
What I am trying to do is create associations, for example if expression 1 is current year units, on every chart a current year count of a metric shows up I want it to be Green.
Whereas there might also be another chart that is count of units by type. I don't want Exp1 here to be green because it is no longer a count by year type of chart. Do themes give you object level control or is it an overall color scheme set where EXP1 on all charts = red, EXP2 = Blue type of deal?
