Hello All,

I was having a very similar problem when making a composite chart with a vertical bar chart and line chart. The bars expand to fill the chart window and I need them to be a fixed width and spaced evenly across the chart so I can line up data points in the line chart with the middle of the bars. I was trying to reproduce you code in vb and was having a problem with the following line:

Teodor Taushanov"]Box box = e.Primitive as Box;

My c# is not as sharp as it should be because i don't use it as much. However, I thought that this would accomplish the same action:

Dim mybox As Box = CType(e.Primitive, Box)

This does not work for the following reasson

Value of type 'infragistics.ultrachart.core.primitives.primitive' cannot be converted to 'infragistics.ultragultraguage.resources.box'

Can any one shed some light on the subject?

TIA

Patrick

i also got the following error "Unable to cast object of type 'Infragistics.UltraChart.Core.Primitives.GraphicsContext' to type 'Infragistics.UltraChart.Core.Primitives.Box'."

 Private Sub ucColumnChart_FillSceneGraph(ByVal sender As Object, ByVal e As Infragistics.UltraChart.Shared.Events.FillSceneGraphEventArgs) Handles ucCoulmnChart.FillSceneGraph
            Dim texts As New List(Of Text)()

            For Each prim As Primitive In e.SceneGraph

                'Dim box As Box = TryCast(prim, Box)
                Dim boxs As Box = Nothing
                boxs = CType(prim, Box)
                If boxs Is Nothing OrElse boxs.DataPoint Is Nothing Then
                    Continue For
                End If

                Dim text As New Text()
                text.labelStyle.HorizontalAlign = StringAlignment.Center
                text.labelStyle.VerticalAlign = StringAlignment.Center
                text.SetTextString(boxs.Value.ToString())
                text.bounds = boxs.rect
                texts.Add(text)
            Next
end sub

i need to include text labels in 3D column chart.

Hi,
