Hi,
  I am trying to follow the example here, http://demos.telerik.com/silverlight/#Chart/Aggregates. I can link the RadGridView with RadChart fine.

However, sometime some column in my data might be empty string or null.

For example, in the http://demos.telerik.com/silverlight/#Chart/Aggregates, if any record does have an empty region or make data, the legend label will be something like "Series X" while the label on the X-Axis will be a number like 1.

Is there a way to change the series or legend label to show something like "N/A" instead?

I look at something like ItemLabelFormat, but I am not sure if that is the solution. Or I should replace empty string with "N/A" on ItemsSource itself?

Thanks,
karlkim

Hi Karlkim Suwanmongkol,

By default, the chart legend gets the name of the data series from the DataSeries.LegendLabel property when you manually populate the chart control. In data binding scenarios it is the SeriesMapping.Legendlabel which holds the legend label.

When using the grouping and aggregation functionality of RadChart the series are auto generated with legend label matching the value on which the data has been grouped.

Hope this will help.
