Hello Rabeek,
You can handle the BeforeLayout or PrePaint events of RadChart and customize the Marker.Appearance.Figure of the legend items to any of the predefined figures (unfortunately there is no predefined dashed line figure):
You can find more information on customizing the legend appearance here.

- Cross
- Diamond
- Ellipse
- Circle
- Rectangle
- Star3
- Star4
- Star5
- Star6
What I can suggest you is to set the Figure of the LegendItem Marker to Rectangle and set custom Height and Width for it so that it looks like a Line:
protected void RadChart1_BeforeLayout(object sender, EventArgs e)
{
RadChart1.Legend.Items[1].Marker.Appearance.Figure = "Rectangle";
RadChart1.Legend.Items[1].Marker.Appearance.Dimensions.AutoSize = false;
RadChart1.Legend.Items[1].Marker.Appearance.Dimensions.Width = 6;
RadChart1.Legend.Items[1].Marker.Appearance.Dimensions.Height = 2;
}
All the best,

This is a going to be a recurring issues for Telerik support. Here is is application scenario -
I have period bar and accumulative line tied in pairs. We got accumulative line by summing up the periodic data.
So they have to be in the same color. Then how can we tell them apart? I think there are 2 options: change line thickness and change pen style. Unfortunately I have to use both. Accumulative curves on my chart looks thinner than the periodic bar, and for future accumulative forecast, I have to show the line type (pen type by your term) difference in the same color.
Since Telerik RadChart is not supporting legend marker by pen style, we are going though the painful process of re-evaluating this toolbox.

Hi brian,

As you can see in our documentation only Line and Spline Series support PenStyle property. Since there is no predefined line Legend Marker, you can't have a dashed/dotted line in the legend. However you may consider adding an image instead of using a predefined shape as legend item marker. This is described here.
