  <p>The above code gives me output:</p>

  <p>Earlier I was able to see the shape with CategoryPlot and LineChart as shown in commented part of the code, but it is not working for XYLineChart.</p>
  
  <p>Please help
  Thanks</p>

  Can I change the color of 
  plot.setDomainCrosshairVisible(true);//Sets Y axis visible blue
  plot.setRangeCrosshairVisible(true);//Sets X axis visible blue
  want to make it black instead of it appearing as blue.</strong></p>
