I have a total of 6 pie chart slices
When I set my OthersCategoryPercent = 3, My Pie Chart Control is showing 3 pie Chart slices (including Others),
When I hover mouse over some of the slices (for Instance "Others") DataItemOver event is fired and its e.DataRow gives me Index = 5 which is legitamate when OthersCategoryPercent = 0, however this slice is not even visible ( it is within Others)
Any way to fix that?
{
e.Primitive != null &&
e.Primitive.Tags.ContainsKey("OthersList");
}
else
sorry, i posted this thinking you were using a 2D pie chart. this is a hack and i don't think it will work in PieChart3D. try just evaluating
e.ColumnLabel == this.UltraChart1.PieChart3D.OthersCategoryText
instead of that stuff with the Primitive's Tags property.
ok, i tested this and found the same thing. Try e.Primitive.DataPoint.Label instead.
here's a condition that also works, but it is a reflection hack:
bool isOthersWedge = e.Primitive.DataPoint == e.Primitive.Layer.GetType().GetProperty("OthersPoint", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.GetProperty).GetValue(e.Primitive.Layer, new object[{});
I'm seeing the same problem on 3D Pie Charts and 3D Doughnut Charts (every other chart that uses "Other's category" works fine). When I use either of those two, the ChartDataEventArgs refers to one of the rows within the Other's Category, not the Other's Category itself. Is there a fix for this or is there someway for me to figure out if the Other's Slice was clicked.
Note: The previous suggestion of comparing the column label (or row label for that matter) does not work. The label is incorrect.
