title: Change series order in stacked charts
body: <p>When I use any of the stacking modes, suddenly series are not in their original order (values from the columns from left to right).</p>
  
  <p>I have found this description on <a href="https://developers.google.com/chart/interactive/docs/gallery/barchart" rel="noreferrer">https://developers.google.com/chart/interactive/docs/gallery/barchart</a> :</p>
  
  <blockquote>
    <p>If set to true, stacks the elements for all series at each domain
    value. Note: In Column, Area, and SteppedArea charts, Google Charts
    reverses the order of legend items to better correspond with the
    stacking of the series elements (E.g. series 0 will be the bottom-most
    legend item). This does not apply to Bar Charts.</p>
  </blockquote>
  
  <p>Which is actually not true (or maybe I am doing something wrong here), because I am really interested in stacked bars. Please check the screenshot below.</p>
  
  <p>Is there any way of changing the order in stacked charts?</p>
  
  <p>No stacking, series are in the correct order:</p>

  <p>Stacked. Series are out of order/reversed order:</p>
