After dynamically applying a palette to a chart, how do I find the color of a particular series on that chart based on the palette application?

My xaml is as follows:
<Controls:RadCartesianChart x:Name="chart" Palette="{Binding SelectedPalette, Mode=TwoWay}" >

If the value of  SelectedPalette changes, I want to know the resulting color of any given Series in the chart's  SeriesCollection in my xaml.cs. The types of these charts may be BarSeries, LineSeries or AreaSeries .

Thanks

Hi Kareema,

The chart series get their brushes from the GlobalEntries array. You can get the color for the series by using the index of the series like this:
int seriesIndex = chart.Series.IndexOf(series);
return chart.Palette.GlobalEntries[seriesIndex].Fill;

Hope this information helps!

Thank you very much Yavor!

I found that this works too:

PaletteEntry? paletteEntryForThisSeries = chart.Palette.GetEntry(series, seriesCounter);
                    if (paletteEntryForThisSeries.HasValue)
                    {
                        var paletteFill = paletteEntryForThisSeries.Value.Fill;
                    }

This only works with up to 8 series on the chart, then fails with an "index out of range" exception. How can I determine the color of all series beyond 8 in the chart?

Hi Greg,

I have just verified that using the GetEntry method of the ChartPalette does not throw an exception in the described scenario. If you keep experiencing problems with this I will ask that you provide us with a small working example that reproduces this issue so that we can test and look for solutions.

Kind regards,

Hello, I'm trying to do a similar thing, but instead of getting this color from code-behind, I need to bind to it from xaml. I've bound my series using a ChartSeriesProvider, and I'd like to display other informations on these series on another control, reusing the color that's chosen by the palette. How would I do that ?

Hello Bruno,

You can either use a converter and use code to get the desired color or you can use the legend item and its Fill property. If you need further assistance I will ask that you open a new thread where you can explain in more details the set up you have and the desired output.
