Hide Item Labels on a Spline Chart in WPF

[Timothy Corey]

I'm trying to hide the item labels on my chart.  There are 52 items on one chart, so the item labels hide the actual line on the chart.  I can't figure out how to turn them off.  The data is generated from the code-behind.  Here is a snippet that shows how I am creating the chart data:

SeriesMapping mySeries = new SeriesMapping();
mySeries.LegendLabel = "Current Year Cash Balance";
mySeries.SeriesDefinition = new SplineSeriesDefinition();
mySeries.SeriesDefinition.Appearance.StrokeThickness = 3;
mySeries.ItemMappings.Add(new ItemMapping("CashBalance", DataPointMember.YValue));
mySeries.ItemMappings.Add(new ItemMapping("Week", DataPointMember.XCategory));
secondaryChart.SeriesMappings.Add(mySeries);
secondaryChart.DefaultSeriesDefinition.ShowItemLabels = false;

secondaryChart.ItemsSource = cashBalanceData.Tables["currentCashBalance"];

Is there a simple way to do this?  Demo code would be most appreciated.  I would prefer the option to do it either in the XAML or the code-behind, since I might want to set the default in the XAML but then change it in the code-behind.

Hi Timothy Corey,

Indeed the desired effect can be accomplished by setting the SeriesDefinition.ShowItemLabels property to false but note that you need to set it on the series definition that you are adding to the RadChart.SeriesMappings collection (i.e. mySeries.SeriesDefinition) and not on RadChart.DefaultSeriesDefinition (DefaultSeriesDefinition is only used if no manual series mappings have been set).

Hope this helps.
