Hello,

In the chart legend, I would like to show a line next to an item instead of a square.  For the ChartView for Winforms I have been unable to find any information on the ability to change the shape.  Is that possible?

 

As I work around, I had an idea to set the top and bottom border as white and increase the border size thinking that I could make the square look like a line I tried that with the following code, but it seems to have no affect. The default black border is sown instead.

LegendItem item = new LegendItem();
item.Element.BackColor = Color.Blue;
item.Element.BorderBottomColor = Color.White;
item.Element.BorderTopColor = Color.White;
item.Element.BorderTopWidth = 3;
item.Element.BorderBottomWidth = 3;
this.mainChart.ChartElement.LegendElement.Items.Add(item);

 

I am able to change the entire border using the following code. It displays a smaller square, which is kind of acceptable but there seems to be a shadow still visible.

LegendItem item = new LegendItem();
item.Element.BackColor = Color.Blue;
item.Element.BorderColor = Color.White;
item.Element.BorderWidth = 3;
this.mainChart.ChartElement.LegendElement.Items.Add(item);

 

Any ideas on how to achieve my goal?

Hello, Chris,    

To be honest, your approach is a tricky one, but it may achieve your goal. Well done!

However, I can suggest you a simpler approach. Actually, the square next to the legend text represents a LegendItemMarker which is a derivative of LightVisualElement. You can handle the ChartElement.LegendElement.VisualItemCreating event, create the default LegendItemElement and assign an ElementShape to the ItemElement.MarkerElement.Shape:




You can also create your own ElementShape and draw a single line as it is demonstrated below:




I hope this information helps. If you need any further assistance please don't hesitate to contact me.
