How to "clip" primitives to chart rectangle
posted

Hi

I dynamically add some lines, boxes and text to a chart in the FillSceneGraph event handler, which works fine, but when I switch to zoom mode and scroll the chart so that my lines, etc. are off the chart they still get drawn over the axes! :(  How can I tell the chart to clip them to the data area like all the "normal" data lines?

Thanks.

    You can try using:

    void ultraChart1_FillSceneGraph(object sender, Infragistics.UltraChart.Shared.Events.FillSceneGraphEventArgs e)

    {

    ChartLayer layer = e.ChartCore.GetChartLayer();GraphicsContext context = new GraphicsContext();

    context.SetClipBounds(layer.OuterBound);

    e.SceneGraph.Add(context);

    // add your primitives here

    }
