title: How do I add custom colors to each slice in a Pie Chart?
body: <p>I know I can set a boolean to true to add varying colors, which seems to be the only way to add different colors per slice.</p>
  
  <p>As far as I can see, I can only do it on the series level...which will just set every slice to one color, which is not what I want. I want to set each slice a different color, but not the default ones given by apache poi.</p>
