Setting ChartModel Series Colors

Hello,

I'm currently trying to write a custom component that extends your Statistics component. When I run my custom component, the data series on the graph is set to a dark green and the legend is set to black. How do I explicitly set the color for each data series that I add (chartModel.addSerie ...) to the ChartModel?

Thanks and regards, Robert

    Hi Robert!

    Is your main problem that "the data series on the graph is set to a another color than its legend" (if so, sounds like a bug that we should fix) or that you for some other reason want's to specify the colors?

    Please let us know

    Hi Henrik,

    Thanks for your reply. It appears that after the basic set of statistics (Maximum thru Failed), if I try to add any additional series, the legend label color is black and the chart display uses the last color that was set (dark green for Failed in this case).

    I thought that if I could explicitly set the legend label colors, that would solve the chart display issue as well. But I can't seem to find anywhere in the API documentation where you can explicitly set chart model colors after you add a series. Any suggestions?

    Thanks in advance, Robert

    You are not able to specify colors from the API. Colors are not bound to certain statistics, but are just assigned to statistics in a first-come-first-serve fashion (whether they're the default set of statistics or your own).

    It seems to me that showing 30-40 series in the same chart would be hard to read regardless of which colors you chose, but on the other hand I think that we could add more colors to the default 16 set of colors if that would help you (I guess you could add ~8 more colors and still be able to tell them apart).

    Sorry if this post sound overexplicit -- you probably know most of these things already
