Does anyone have some sample code for a simple scatter-line chart? I have done many of the 2D charts, but haven't done the scatter chart yet. I've seen one example of a scatter-line chart and can't get it to display. Any help would be greatly appreciated. My Y axis is min 0 & max 50 with a single increment of 25. My X Axis is Planets, with the various planets plotted on the chart (assigned values between 5 and 45). I get no errors, but I can't get it to display.

I will forward your post to Developer Support. They should be able to assist you with displaying the data point labels.
No good, still get index out of bounds. Here is how I am filling my data table:
dt.Columns.Add(
"label", GetType(String))
"column1", GetType(Double))
"column2", GetType(Double))
dt.Rows.Add(
New Object() {"datapoint a", 5, 20})
New Object() {"datapoint b", 7, 25})
New Object() {"datapoint c", 9, 35})
New Object() {"datapoint d", 11, 15})
New Object() {"datapoint e", 13, 28})
New Object() {"datapoint f", 15, 22})
New Object() {"datapoint g", 17, 22})
New Object() {"datapoint h", 19, 25})
New Object() {"datapoint i", 21, 33})
New Object() {"datapoint j", 23, 15})
New Object() {"datapoint k", 25, 28})
New Object() {"datapoint l", 27, 27})
New Object() {"datapoint m", 29, 20})
New Object() {"datapoint n", 31, 25})
New Object() {"datapoint o", 33, 31})
New Object() {"datapoint p", 35, 15})
New Object() {"datapoint q", 37, 28})
New Object() {"datapoint r", 39, 22})
iScatterChart.DataSource = dt
iScatterChart.DataBind()
iScatterChart.ScatterChart.ChartText(0).Visible = True
And of course, the "datapoint x" label is what I'm expecting to display.
Yes, please try to set the property after databinding. The sample does databinding before setting the property.
I've reviewed that sample, but get an index out of bounds error when addressing ChartText property. Should I be addressing it after I databind?
