title: Different color for different series in XYline chart JFreeChart
body: <p>I have created XY line chart using JFreeChart, having two datasets, I want both the lines to be in different colors. I tried using following code-</p>
  
  <pre><code>  XYPlot plot = chart.getXYPlot();
    XYItemRenderer xyir = plot.getRenderer();
    xyir.setSeriesPaint(0, Color.GREEN);
    plot.setDataset(0, xyDataset1);
  
    xyir.setSeriesPaint(1, Color.blue);
    plot.setDataset(1, xyDataset2);
  </code></pre>
  
  <p>Also I have tried using following code, where I am using different renderer (don't know whether this is correct way to do it)-</p>
  
  <pre><code>  XYPlot plot1 = chart.getXYPlot();
    XYPlot plot2 = chart.getXYPlot();
  
    XYItemRenderer xyir1 = plot1.getRenderer();
    xyir1.setSeriesPaint(0, Color.GREEN);
    plot1.setDataset(0, xyDataset1);
  
    XYItemRenderer xyir2 = plot2.getRenderer();
    xyir2.setSeriesPaint(1, Color.blue);
    plot2.setDataset(1, xyDataset2);
  </code></pre>
  
  <p>In both the cases its printing both the lines in blue color.
  What's wrong?? Any suggestions??</p>
