How do you suppress the leaderline if you return a null string for the label?

I only want to show all slices of a piechart, but not the label and leaderline if the data_value is < 1000.

  foreach (Primitive p in primitives)
  {
    e.SceneGraph.Remove(p);
  }
}

How would you do this in the 2007 Vol.2 version?  I have created a custom layer for the FillSceneGraph(SceneGraph scene) method.  But have not found the right methods to use instead of the FillSceneGraphEventArgs e ones available in Vol.3 version.

Thanks

Can you help me with the details of how to suppress the leaderlines and labels for slices of the piechart that are < $1000.

 I am trying to do this with v7.2 code...

 Thanks

----------------------------------------------------------------------------------------------------------------------------------------------------------

In my driver code I have the hook to access the  FillSceneGraph method...

  // add the layer
     igChart.Layer.Add("My Layer", new MyLayer());
     igChart.UserLayerIndex = new string[ {"Default", "My Layer"};
     igChart.InvalidateLayers();
  
     BindDataToChart(igChart, dt);

In my layer class I have the following routine to manipulate the graph Scene...

 public void FillSceneGraph(SceneGraph scene) 
 {
  PrimitiveCollection primitives = new PrimitiveCollection();
  
  /* first let's get a reference to all the columns/bars in the chart, then manipulate them. */
  ArrayList allSlices = new ArrayList();   
  foreach (Primitive p in scene)
  {
   Wedge w = p as Wedge;
   if (w != null)
   {
    allSlices.Add(p);
   }
  }
  
  foreach (Wedge w in allSlices)
  {
   if ((double)w.Value > 1000)
   {

       int index = 0;
       //int index = b.SceneGraph.IndexOf(label);  <-------- What v7.2 codes needs to go here...

      if (index == 2)
      {

           //labels follow the leaderlines, 2 spots further in the collection. <-------- What v7.2 codes needs to go here...
           //Line line = b.SceneGraph[index - 2] as Line;                        <--------

          Line line = null;
          if (line != null)
          {
              primitives.Add(line);
          }
       }
      primitives.Add(w);
   }
  }
  
  //foreach (Primitive p in primitives)    <---------- What v7.2 codes needs to go here...
  //{                                                  <----------
  //e.SceneGraph.Remove(p);             <----------
  //}                                                  <----------

The code should be identical with one exception: replace e.SceneGraph with scene, which is the only parameter in your FillSceneGraph method.

Let me know if that works for you.

It worked.  I only had to parse the label text to get the data value, since I had formatted it <Percent_Value>% $<Data_Value> <Item_Label>.

Thank you for your help.
