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

You probably have added the gauge assemblies as well to your project and VS is looking for infragistics.ultragultraguage.resources.box rather than Infragistics.UltraChart.Core.Primitives.Box.

Try using:

Dim mybox As Infragistics.UltraChart.Core.Primitives.Box = CType(e.Primitive, Infragistics.UltraChart.Core.Primitives.Box)

Teodor -

The code compiled ok but tripped a runtime error:

Unable to cast object of type 'Infragistics.UltraChart.Core.Primitives.GraphicsContext' to type 'Infragistics.UltraChart.Core.Primitives.Box'.

Try

If mybox Is Nothing Or mybox.DataPoint Is Nothing Then

lbl_Overview_user_messages.Text += "myBox is nothing <br/>"

Return

End If

lbl_Overview_user_messages.Text += "myBox is Something <br/>"

If dWidth <= 0 Then

Return

End If

Return

End Try

End Sub

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,

I have two charts in page,  I filled chart 2 when the user clicked column bar of chart1.

The problem are width size of column bar chart2.

Thanks
