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

This is error --> ex.message "Specified cast is not valid."

Thanks.

Update this code was working in 7.2 however it seems to have broken in 8.1.... which version are you using?

I'm using 7.1version and asp.net 2003.

Thanks

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.
