title: Show a chart with very high and very low values
body: <p>I have a bar chart that shows sales against targets for categories as percentages of the targets.  </p>
  
  <p>The problem I have is that sometimes one or two of the categories will overperform making the chart hard to read.</p>
  
  <p>Capping the Y axis at 200% has been deemed unacceptable as the usres want to see the top of the bar.</p>
  
  <p>The users have asked if it is possible to crop a section out of the middle, so you would see 0% - 150%, then a gap then (top of high bar - 10%)% to (top of high bar + 10%)%.  I dont think this can be done using the built in chart control.</p>
  
  <p><img src="https://i.stack.imgur.com/CNqWY.png" alt="Here is a sample of how the chart looks"></p>
  
  <p>Does anyone have any ideas of a good way to handle this situation?</p>
