title: how to reset Highchart chart width in percentage on Button click
body: <p>I want to change <strong>highchart's width</strong> on button click, I know I can do it using <code>chart.setSize</code> function, but it sets the width only in <strong>pixels</strong>. But I need to set the width in <strong>percentage</strong>.</p>
  
  <p>Here is <a href="http://jsfiddle.net/HMDHP/2/" rel="nofollow">the sample JSFiddle</a>, in which I have tried to reset the width in 3 ways. Only Button 1 works, but not the remaining 2. </p>
