title: Microsoft Excel Pie Chart bug
body: <p>Pie chart percentage not calculated correctly by excel. In the picture you can see that the c and d values are exactly the same, but for some reason "c" has a higher percentage denoted to it and I can't figure out why.</p>
  
  <p>The values are a-21; b-5; c-11; d-11; e-3; f-5; g-1; h-39. On the pie chart the percentage received is a-22%; b-5%; c-12%; d-11%; e-3%; f-5%; g-1%; h-41%</p>
