Answered How to change series colour

Hi,

I'm trying to programmatically change the fill colour of the series on my chart and for some reason I'm not getting it to work.

This is the code I'm currently using.

radChart1.SkinsOverrideStyles = false;

            chartSeries.Appearance.FillStyle.FillType = Telerik.Charting.Styles.FillType.Gradient;

            chartSeries.Appearance.FillStyle.FillSettings.GradientMode = Telerik.Charting.Styles.GradientFillStyle.Horizontal;

            chartSeries.Appearance.FillStyle.MainColor = Color.FromArgb(255, 55, 96, 145);

            chartSeries.Appearance.FillStyle.SecondColor = Color.FromArgb(255, 184, 204, 228);



            radChart1.UpdateGraphics();

Obviously I'm either missing something or the above code is completely wrong, can someone help please?

Regards,

Guy

Hello,

Thank you for providing us with your sample.

Some of the RadChart's Skins are more complex than others and the palette overrides the Gradient Filltype. In such cases you should use the ComplexGradient FillType like this for example:

// Chart styling

radChart1.SkinsOverrideStyles = false;

chartSeries.Appearance.FillStyle.FillType = Telerik.Charting.Styles.FillType.ComplexGradient;

chartSeries.Appearance.FillStyle.FillSettings.GradientMode = Telerik.Charting.Styles.GradientFillStyle.Horizontal;

chartSeries.Appearance.FillStyle.FillSettings.ComplexGradient.Add(new GradientElement(Color.FromArgb(255, 55, 96, 145), 0));

chartSeries.Appearance.FillStyle.FillSettings.ComplexGradient.Add(new GradientElement(Color.FromArgb(255, 184, 204, 228), 1));

This is edited code snippet from your project so following the above approach should change your series' color.

Hope this helps.
