xaxis item labeltext for stacked column programatically

[Joel]

I am creating a an htmlchart completely in the code behind.  I utilized one of the demos. 

I now want to extend that chart as a stacked column.  It works well.

Problem I am having is having the x-axis labels showing up.  if I do this, I get an index error

ch1.PlotArea.XAxis.Items.Item(0)...

Since I am declaring each series in the code, and each categoryseriesitem in a row loop, it is not databound in a traditional manner.  The following does not throw an error, but the x-axis label is not visible either
ch1.PlotArea.XAxis.DataLabelsField = "Name"

Any suggestions? This is close to being done, but this is the last piece.

Please disregard.  I had to add xaxis items within the categoryseriesitem loop and it works fine.

For Each row As DataRow In GetChartDataE().Rows
  ..add categoryseriesitems

 ch1.PlotArea.XAxis.Items.Add(row("Name"))
