title: how to add above each column a different pie chart
body: <p>i have a column chart for male distribution of my data .
  my question if it's possible to add on the same chart , above each column a pie chart to display other data (such as cities ) for each male ?</p>
  
  <p>EDIT : 
  i saw this example <a href="http://www.highcharts.com/demo/combo" rel="nofollow">http://www.highcharts.com/demo/combo</a>
  on thier demo and that what gave me the idea. but in the code they display the pie chart by saying specificly where to put it not based on the x-axis . any help if it is possible ? because the pie chart doesn't have a x y axis.</p>
