How do change to the color of a bar series programmatically?

[Louay Jabry]

I need to programmatically create my barseries and assign a different color of my choosing for each series. In Line series, it is easy. I set the Stroke color. I couldn't find anything equivalent for the bar series.

Hello Louay,

You can achieve the desired appearance by setting the BarSeries.DefaultVisualStyle property like this:

BarSeries series = new BarSeries();
series.DataPoints.Add(new CategoricalDataPoint() { Category = "C1", Value = 11 });
series.DataPoints.Add(new CategoricalDataPoint() { Category = "C2", Value = 5 });
series.DataPoints.Add(new CategoricalDataPoint() { Category = "C3", Value = 7 });
series.DataPoints.Add(new CategoricalDataPoint() { Category = "C4", Value = 17 });

Style style = new Style(typeof(Border));
style.Setters.Add(new Setter(Border.BackgroundProperty, new SolidColorBrush(Colors.LightGray)));
series.DefaultVisualStyle = style;

RadChart1.Series.Add(series);

Hope this helps.
