title: How to arrange the data in a Pivot Chart? (stacked column chart)
body: <p>I generated a pivot chart from a pivot table. The chart type is stacked columns. The problem with the pivot is that it generated automatically the order of the stacks and I can't set them in the order I want
  Do you know if I can rearrange the stacks order in a Pivot Chart?
  I want to do this because I have some other chart type for some data (line) and the lines need to be on the same level with the stacks.
  Any idea?
  Thanks!</p>
