I would have thought it would be possible to set the shape of the legend like this:

legend.BorderStyle.Shape = BorderShape.RoundedRect;

But BorderStyle is null. Ok, I'll create a new border style instance:

legend.BorderStyle = new NBorderStyle(BorderShape.RoundedRect);

Nope, NBorderStyle is an abstract class. What class should I use? I can't seem to find this information anywhere in the online documentation.

Hi David,

More information can be found at:

The following code snippet shows how to apply a rounded border to the legend, as well as how to turn off the legend grid:

nChartControl1.Panels.Clear();
NLegend legend = new NLegend();
legend.Mode = LegendMode.Manual;
legend.UseAutomaticSize = true;

for (int i = 0; i < 3; i++)
{
NLegendItemCellData licd = new NLegendItemCellData();
licd.Text = i.ToString();
legend.Data.Items.Add(licd);
}

// optionally turn off border
legend.HorizontalBorderStyle.Width = new NLength(0);
legend.VerticalBorderStyle.Width = new NLength(0);
legend.OuterBottomBorderStyle.Width = new NLength(0);
legend.OuterTopBorderStyle.Width = new NLength(0);
legend.OuterLeftBorderStyle.Width = new NLength(0);
legend.OuterRightBorderStyle.Width = new NLength(0);

// increase padding
legend.Padding = new NMarginsL(10, 10, 10, 10);

// set a border
NStrokeBorderStyle strokeBorder = new NStrokeBorderStyle(BorderShape.RoundedRect);
legend.BorderStyle = strokeBorder;
legend.BackgroundFillStyle = new NColorFillStyle(Color.LightGray);
nChartControl1.Panels.Add(legend);

Hope I helped - let me know if you have any questions or comments.

Very helpful, thank you.

Is there a way to set the dockstyle to "top" without the new border expanding to fill the width of the control? I realise that that is normal behaviour for .NET, but then that doesn't happen with the default border.

I've also noticed that the Shadow of the legend still has square corners.

Hi David,

1. Is there a way to set the dockstyle to "top" without the new border expanding to fill the width of the control? I realise that that is normal behaviour for .NET, but then that doesn't happen with the default border.
No we don't have this feature yet - you can place the legend at the top by using Location/Content alignment position:

legend.Location = new NPointL(new NLength(50, NRelativeUnit.ParentPercentage), new NLength(0));
legend.ContentAlignment = ContentAlignment.BottomCenter;

but that way you'll loose the docking functionality that related to other panels.

2. I've also noticed that the Shadow of the legend still has square corners.
Hmm that can easily be fixed - I'll make sure we have a shadow property for the border in the next edition or SP of the control.

Questions or comments - please feel free...

Best regards,
Bob
