LineSeries Dashed / Dotted Line Style

[pratik mehta]

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

Hi pratik mehta,

The recommended approach to styling all elements consistently, including legend items would be the CreateItemStyle delegate. Also, check this blog post for details.
