title: Setting color of pie chart slices and legend
body: <p>Does anybody know how to set the color of the slice/legend of a PowerPoint 2010 Pie Chart in C#?  I can't make anything I read from the MSDN site work. I can't work out the proper way to get the correct object and property.</p>
  
  <p>Edit:
  Well, I thought about adding code, but what I have is not working, so I wasn't sure how helpful or informative it would be. I can't figure out which object/method/property to use to get access to the pie chart slice color. I've tried Point, LegendKey, LegendEntry, Legend, and associated methods/properties with each. I've tried many things that aren't even represented in my code anymore.</p>
  
  <p>But, for what it's worth, this is what my code is now:</p>
  
  <pre><code> PowerPoint.Series series = (PowerPoint.Series)xlChart.SeriesCollection(1);
   PowerPoint.Point point = (PowerPoint.Point)series.Points(xlCol);
  
   point.Interior.ColorIndex = Convert.ToInt32(dataArray[2, i]);
  
   PowerPoint.Legend legend = (PowerPoint.Legend)xlChart.Legend;
   PowerPoint.LegendEntry lentry = (PowerPoint.LegendEntry)legend.LegendEntries(1);
  </code></pre>
