title: Silverlight PieSeries custom LegendItem with Buttons (and FormattedRatio percentage)
body: <p>For my PieSeries, I'd like to have the legend with buttons which have the Fill colour of the relevant slice, I would also like the buttons to have the percentage as shown in the tooltip using the FormattedRatio. Here's what I have so far:</p>
  
  <p><img src="https://i.stack.imgur.com/MInOR.png" alt="PieSeries image with buttons and orange slices"></p>
  
  <p>Unfortunately, as can be seen all the slices have now gone orange, which forums have said is a standard problem but provide no obvious reason, also "FormattedRatio" is not available to the LegendItem. (I would like it to say Example B : 10.17%.)</p>
  
  <p>Does anyone know how I can get colours back and how I can use the percentage in the legendItem?</p>
  
  <p><strong>Edit:</strong></p>
  
  <p>Have been able to change the background of the slices using <a href="https://stackoverflow.com/a/7757676/1372191">this answer</a> but the LegentItems don't change according to the new colour scheme. </p>

  <p>The colours are correct - I'm using test data which is wrong.</p>
