Awesome! Thanks!

it would be something like this:

For Each p As Primitive In e.SceneGraph
   If TypeOf p Is Polyline Then
      Dim polyline = CType(p, Polyline)
      'do stuff
   End If
Next

How would you write this in vb? i'm not having any luck checking primitive against polyline.

Are you calling DataBind on your series after assigning DataSource and ValueColumn properties? You should be able to see the Points collection populated and count should be greater than zero after calling series.DataBind()

Got the dynamic data setting figured out... here's my code:

 NumericSeries  sLife = GetLifeSeries();

UltraChart1.CompositeChart.Series.Add(sLife);

UltraChart1.CompositeChart.ChartLayers[0].Series.Add(sLife);

NumericSeries  sChanges = GetChangesSeries();

UltraChart1.CompositeChart.Series.Add(sChanges);

UltraChart1.CompositeChart.ChartLayers[1].Series.Add(sChanges);

Now, back to the margin setting for x axis... I'm ready to set it, but need to get number of data points in the column chart, using the series...

I tried:

// set the margin on the x-axis to make sure points line up with columns

LocationType.Percentage;

UltraChart1.CompositeChart.ChartLayers[1].AxisX.Margin.Near.Value = marginPercent;

LocationType.Percentage;

UltraChart1.CompositeChart.ChartLayers[1].AxisX.Margin.Far.Value = marginPercent;

But, the series.Points.Count - is zero!!!

Using the debugger, I could not find what to use to find the number of columns from the series. Can you help?
