title: Setting currency format for labels of vertical axis in jFreeChart
body: <p>The essential of question is declared at the title.</p>
  
  <p>More details: I have the Time series chart, and vertical axis should has labels in currency format like this</p>
  
  <pre><code>$100, 000, 000
  $50, 000
  ...
  </code></pre>
  
  <p>Now I have the same labels, but without dollar sign and range delimiter.</p>
  
  <p>For horizontal axis I used this approach:</p>
  
  <pre><code>DateAxis axis = (DateAxis) plot.getDomainAxis();
  axis.setDateFormatOverride(new SimpleDateFormat("yyyy"));
  </code></pre>
  
  <p>And it works.</p>
  
  <p>When I try to do similar</p>
  
  <p>ValueAxis valueAxis = (ValueAxis) plot.getRangeAxis();</p>
  
  <p>I can't find any method to format labels.</p>
  
  <p>Please, help me. </p>
