Hi Team,
We have purchased RadControls_for_Silverlight5_2013_1_0403_Dev.msi. We have a requirement, where if we have a null value in the collection.. we have to show a dotted line in Rad Chart line series, that looks like connecting points. Currently by default it is shown as a gap between point marks, which is so annoying.
Please help me!

Hi Sowjanya,
RadChart provides three EmptyPoint Behaviors out-of-the-box. I have attached screenshots of the three modes.
The closest functionality to what you require that is available out-of-the-box is Drop. If this is good enough for you, then you can enable it by setting *SeriesDefinition.EmptyPointBehavior to EmptyPointBehavior.Drop.
If you however require dotted line over empty points, then you use the workaround demonstrated in the attached project. It requires using a separate series for the dotted effect and a separate ItemsSource.
I hope this helps.

Hello Akbar Basha,
I am not sure that I understand you requirement. The Gap mode is applied for empty values which have sense in a Cartesian chart visualization. On the other side I am not sure how the empty value should be drawn as a gap in pie chart. The size of the slices depends on the data point's value and if there is not value nothing should be drawn. In RadChart's PieSeries definition the Gap mode is the same as the Drop mode - the empty data points are not drawn on the pie.
Also, I want to note you that RadChart is out old charting component which has many known issues and limitations. Instead I recommend using the new RadChartView suite that has better implementation and improved performance. You can read about the differences between the charts in the RadChart vs. RadChartView help article.
