Customize Legend Items on RadChart DataTable

[Ryan]

I have a radchart with a dataTable but no legend.  I know it is possible to customize items in the chart legend, but is it possible to customize the legend on the radchart dataTable?

Hello Ryan,

Unfortunately it is not possible to customize the legend items of the RadChart DataTable. Please, excuse us for the inconvenience caused.

There is a way I found to customize the legend, but only for what's displayed.  Let's say you have a Data.DataTable that contains Description and Value fields.  You can customize the legend by creating another column for the legend where you want to show the Description field if they're all <= 10 characters long and the Value if the Description is > 10 characters.

dt.Columns.Add(New Data.DataColumn("legend"))
For Each row As Data.DataRow In dt.Rows
  If Len(row.Item("description")) > 10 Then
    blnUseValueForLegend = True
    Exit For
  End If
Next
If blnUseValueForLegend Then
  For Each row As Data.DataRow In dt.Rows
    row.Item("legend") = row.Item("value").ToString
  Next
Else
  For Each row As Data.DataRow In dt.Rows
    row.Item("legend") = row.Item("description").ToString
  Next
End If

Then, you can say in your chart RadChart1.Series(0).DataLabelsColumn = "legend" and you're done.
The whole thing is calculated dynamically as run-time.
