title: pChart 2.x graph plots scale using decimals instead of whole numbers
body: <p>I'm working on stats containing a number of visits and the scale on pChart is showing decimals instead of whole integers. </p>
  
  <p>The default setting is creating scales with fractions similar to below:</p>
  
  <pre>
  0  0.2  0.4  0.6  0.8  1.0  1.2
  |===

  </pre>
  
  <p>That doesn't work as you can't visit a site 1.2 times. </p>
  
  <p>I was trying to make scale only with whole numbers (0, 1, 2 etc.) with <code>"Mode"=&gt;SCALE_MODE_MANUAL</code> parameter but I failed. </p>
  
  <p>How do I set or force pChart to plot using whole numbers on the axis?</p>
