Hi,
I would like to know if we can trap the legend click event ?
also is it possible to crontrol the color of the pie chart are?
Thanks
Right now the default legend only supports square icons for column type charts, line icons for line/spline charts and symbol icons for scatter charts. To get custom icons, like circle, rectangle and High-Low you would have to custom draw them. The way this is typically done is by handling FillSceneGraph event. There you have to loop through the existing primitives in e.SceneGraph and locate the ones that represent the legend items (they have "Legend" string in their Path). Then you can modify their dimensions or replace them with new primitives.
Hi ,
Regarding the legend in a composite chart i had a requirement of displaying the graph in a windows application with legend as shown in the below snap shot
I am not able to produce the legend as required.
Can you please suggest
Thanks in advance
By default the legend is not interactive. Try using ChartDrawItem event to set up additional properties on the legend primitives to make them clickable:
private void ultraChart1_ChartDrawItem(object sender, Infragistics.UltraChart.Shared.Events.ChartDrawItemEventArgs e){ if (e.Primitive.Path != null && e.Primitive.Path.IndexOf("Legend") != -1){ e.Primitive.Caps |= PCaps.HitTest | PCaps.Tooltip; if (e.Primitive.Row == -1 && e.Primitive.Column == -1){ e.Primitive.Row = e.Primitive.Column = 0; } e.Primitive.Chart = this.ultraChart1.ChartType; }}
After you do this, ChartDataClicked will fire when you click the legend
The colors of the pie chart can be controlled in a number of ways. You can refer to the following help link for more information about using the chart's different color models:http://help.infragistics.com/Help/NetAdvantage/NET/2007.3/CLR2.0/html/Chart_Appearance.html
