title: Modify Z-index on Series object in Excel 2010
body: <p>I am using excel 2010.</p>
  
  <p>I have a chart diagram on which i put a rectangle to surround the highest column bar.</p>
  
  <p>In order to make things more readable, i would like to place this rectangle on the chart but NOT in front of the lines/bars/etc...It has to be behind them.</p>
  
  <p>Shape objects (like my rectangle) have a ZIndex property than can be modified in order to achieve that. Thing is, it seems impossible to put that behind the elements of my chart, nor the chart itself.</p>
  
  <p>The main reason is because Chart objects and Series objects (which are the columns inside my chart) doesn't have a Z-Index property.</p>
  
  <p>Is there a way which could allow me to achieve this ? Other than modifying ZIndex property ?</p>
