Hi,

I want to display some lines in chart as dotted or dashed. I am using below code to display line as dotted as dashed.
In my code i am not generating Legend items manually.

private Style GetLineSeriesStyle(int lineType)

{

Style lineStyle;

Style pathStyle;

switch (lineType)

{

case 1:

pathStyle = new Style(typeof(System.Windows.Shapes.Path));

pathStyle.Setters.Add(new Setter(Shape.StrokeDashArrayProperty, "2"));

pathStyle.Setters.Add(new Setter(Shape.StrokeThicknessProperty, 2));

pathStyle.Setters.Add(new Setter(Shape.StrokeProperty, new SolidColorBrush(Colors.Yellow)));

lineStyle = new Style(typeof(Telerik.Windows.Controls.Charting.SelfDrawingSeries));

lineStyle.Setters.Add(new Setter(SelfDrawingSeries.BorderLineStyleProperty, pathStyle));

break;

case 2:

pathStyle = new Style(typeof(System.Windows.Shapes.Path));

pathStyle.Setters.Add(new Setter(Shape.StrokeDashArrayProperty, "2"));

pathStyle.Setters.Add(new Setter(Shape.StrokeThicknessProperty, 2));

pathStyle.Setters.Add(new Setter(Shape.StrokeProperty, new SolidColorBrush(Colors.Red)));

lineStyle = new Style(typeof(Telerik.Windows.Controls.Charting.SelfDrawingSeries));

lineStyle.Setters.Add(new Setter(SelfDrawingSeries.BorderLineStyleProperty, pathStyle));

break;

default:

Random oRandom = new Random();

Color oColor = Color.FromArgb(Convert.ToByte(oRandom.Next(100, 255)), Convert.ToByte(oRandom.Next(100, 255)), Convert.ToByte(oRandom.Next(100, 255)), Convert.ToByte(oRandom.Next(100, 255)));

pathStyle = new Style(typeof(System.Windows.Shapes.Path));

pathStyle.Setters.Add(new Setter(Shape.StrokeProperty, new SolidColorBrush(oColor)));

pathStyle.Setters.Add(new Setter(Shape.StrokeLineJoinProperty, "2"));

pathStyle.Setters.Add(new Setter(Shape.StrokeThicknessProperty, 2));

lineStyle = new Style(typeof(Telerik.Windows.Controls.Charting.SelfDrawingSeries));

lineStyle.Setters.Add(new Setter(SelfDrawingSeries.BorderLineStyleProperty, pathStyle));

break;

}

return lineStyle;

}

Now in follwing example My series color and legend color are mismatching.
i tried by commenting below code

pathStyle.Setters.Add(new Setter(Shape.StrokeProperty, new SolidColorBrush(Colors.Red)));

in above code base. but in that case i am not able to see any line in my chart area.

Can you please let me know hot display dashed ot dotted line without touching Color property.
And i do not want to add Legend manually.

Thanks
