Is there a way to change the labelmode based on the data?

Something along the lines of

     

if (pieSeries.Values[i] > .1){
        //I want to change the labelMode of this value to Center on the pie chart
        pieSeries.LabelMode = PieLabelMode.Center;
        }else {
        //I want to change the labelMode of this value to SpiderNoOverlap on the pie chart
        pieSeries.LabelMode = PieLabelMode.SpiderNoOverlap;
        }

Also how can I adjust the lengths of the lines for SpiderNoOverlap.  I tried the following without success.

      pieSeries.DataLabelStyle.ArrowLength = new NLength(1.0f,NRelativeUnit.ParentPercentage);
      pieSeries.DataLabelStyle.ArrowPointerLength = new NLength(1.0f,NRelativeUnit.ParentPercentage);

Hi Jerrry,

This obviously relates to SSRS - in this case you simply need to use the context.Document, instead of nChartControl and you'll be OK - for example:

context.document.RootPanel.ChildPanels.Clear();

However in your case we think that you should not clear the panels collection - the pie chart is already created and configured - you just need to alter some label settings so the code should simply omit the Clear line of code:

NChart1.Panels.Clear();

Hope this helps - let us know if you meet any problems or have any questions.
