When designing report chart in ActiveReportJs Designer
I want to color the chart with the color I want with using hex color list in dataSet.
Currently, I received the hex color value list in dataSet.
like ([{map=#ffb240}, {map=#a8d277}, {map=#59b0f6}, …])
Is there a way to dynamically implement the chart color on custom palette based on the color value of the dataSet?

Hello,
A color value in the chart palette could be an expression that evaluates at runtime, so this functionality is supported.

Thanks for reply.
how can i evaluates list values using expression?
when i using that list at expression, it only evaluates first list value…
list : ([{color=#ff0000}, {color=#00ff00}, {color=#0000ff}, …])

I see, so you have a separate dataset including color values and you want to map it to a chart palette color.
There is no built-in functionality that would allow achieving that because a chart palette must contain multiple values, one per color.
The only workaround I can suggest is to modify a report template programmatically by pulling the color values and setting them for the chart color palette.
