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 Jerry,
One solution would be to use anchor panels for the labels that you wish to exclude from automatic layout. The following code snippet shows how to achieve this:

   nChartControl1.Panels.Clear();

   NPieChart pieChart = new NPieChart();

   nChartControl1.Panels.Add(pieChart);

   NPieSeries pieSeries = new NPieSeries();
   pieChart.Series.Add(pieSeries);

   pieSeries.Values.Add(10);
   pieSeries.Values.Add(10);
   pieSeries.Values.Add(10);
   pieSeries.LabelMode = PieLabelMode.SpiderNoOverlap;

   pieSeries.Labels.Add("One");
   pieSeries.Labels.Add("");
   NDataLabelStyle dls = new NDataLabelStyle();
   dls.Visible = false;
   pieSeries.DataLabelStyles[1] = dls;
   pieSeries.Labels.Add("Three");

   NLabel label = new NLabel("Two");
   label.ContentAlignment = ContentAlignment.MiddleCenter;
   label.TextStyle = (NTextStyle)dls.TextStyle.Clone();
   NAnchorPanel anchorPanel = new NAnchorPanel();
   anchorPanel.ChildPanels.Add(label);
   anchorPanel.Anchor = new NPieDataPointAnchor(pieSeries, 1, 1, StringAlignment.Center);

   nChartControl1.Panels.Add(anchorPanel);

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