Set series colors

created 12 years ago

Hi,
I have a chart where I'm adding series at runtime. Some of the series I want change their colors to match a related series. But after I'm done adding the chart series, the series colors are not yet set, so the pallette colors get assigned every time. I want to use the pallete colors but after colors are assigned, i need to go through the series and match the color of some series to that of its related series. When do the series colors get set? Is there an event i can subscribe to? Or a way to force the color assignments at runtime?
(I'm using Series.View.Color to set the colors of the series but since the colors haven't yet been set, they all end up Color.Empty)

(I'm trying to set line series colors to match that of related bar series.)
Thanks,
Andy

    Use the ChartControl.GetPaletteEntries Method to obtain the series color:

    C#
    PaletteEntry[] palette = WebChartControl1.GetPaletteEntries(WebChartControl1.Series.Count);  
Color seriesColor = palette[<SeriesIndex>].Color;

    Then you can set a new color either by using Series.View.Color or in the CustomDrawSeries event handler.

          I'm using WPF ChartControl BarStackedSeries2D and need the same control on the colors. GetPaletteEntries is not support. Please, advice

            Hi Sarit,

            Palette entries can be obtained using the Palette[index] syntax. Please try this approach and let me know if you have any questions.
