Thanks Max.  The triangles are actually represented by a numerical value just like the columns but my user likes the triangle for some reason.  If I just use another column to display this data, most of the values are "0".  How can I display the column and number if the value is greater than "0" but display nothing if the value is "0"?

Hello Bill,

I am following up to see were you able to use the suggestion Max has provided using stored procedure.

Thanks,

I'm still a little unclear how to get my stored procedure fed datasource to the FillSceneGraph sub and how to loop through the chart but I will give it my best shot.  Thanks Max.

Something like this:

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        UltraChart1.Data.DataSource = New Integer(,) {{1, 1}, {2, 2}, {3, 3}, {4, 4}}
    End Sub

    Private Sub UltraChart1_FillSceneGraph(ByVal sender As System.Object, ByVal e As Infragistics.UltraChart.Shared.Events.FillSceneGraphEventArgs) Handles UltraChart1.FillSceneGraph
        If e.Grid.Count = 0 Then
            Return
        End If

        Dim itemsPerGroup = 2
        Dim position = 2

        Dim xAxis As IAdvanceAxis = e.Grid("X")
        Dim yAxis As IAdvanceAxis = e.Grid("Y")

        Dim s As Symbol = New Symbol(SymbolIcon.Triangle, SymbolIconSize.Large)
        Dim pos = 1 + position * (itemsPerGroup + UltraChart1.ColumnChart.SeriesSpacing)
        Dim value As Double = 2.5
        s.point = New Point(xAxis.Map(pos), yAxis.Map(value))
        s.PE.Fill = Color.Blue
        e.SceneGraph.Add(s)

        position = 3
        value = 3.2
        pos = 1 + position * (itemsPerGroup + UltraChart1.ColumnChart.SeriesSpacing)
        s = New Symbol(SymbolIcon.Triangle, SymbolIconSize.Large)
        s.point = New Point(xAxis.Map(pos), yAxis.Map(value))
        s.PE.Fill = Color.Blue
        e.SceneGraph.Add(s)
    End Sub

Do you have a VB.NET code example of how I could loop through the SceneGraph to accomplish this?

That would be much harder to do, because additional columns introduce additional space that needs to be allocated to specific groups of columns. When the column's value is 0, the chart will display a column with 0 height, but the width of the column still has to be accounted for. As a result, you will have a gap where column's value is a zero. Personally, I think adding triangle symbols is much easier.
