How I can add custom LegendItem to the Legend instead of the automated Legend items

Platform: WinForms |
Control: Chart |

It is possible to add custom LegendItem to the Legend instead of the automated Legend items. For this we have to use the event Legend.FilterItems of the chartControl. This event is raised before the legend items are rendered.

Here is the code snippet.

C#

private void Legend_FilterItems(object sender, ChartLegendFilterItemsEventArgs e)

{

e.Items.Clear();

ChartLegendItemsCollection item = new ChartLegendItemsCollection();

LegendItem l = new LegendItem();

LegendItem l1 = new LegendItem();

l.ItemStyle.BorderColor=Color.Black;

l.Text="Test1";

l1.ItemStyle.BorderColor = Color.Blue;

l1.Text = "Test2";

item.Add(l);

item.Add(l1);

e.Items = item;

}
