How to display label on the right side outside of chart using JavaFreechart?

[psgpsg]

Hi All,
In my application, i have created the bar chart using the JFreechart and also added the Value marker for y= 100 and its working fine.From the below code i get the label on right side (but inside the chart). But i need to add the text against the y = 100 on right side (outside the chart).

  Marker target = new ValueMarker(100);
  target.setPaint(Color.BLACK);
  target.setLabel("Test");
  target.setLabelAnchor(RectangleAnchor.RIGHT);
  target.setLabelTextAnchor(TextAnchor.BASELINE_RIGHT);
  target.setLabelFont(new Font("Arial", Font.PLAIN, 16));
  p.addRangeMarker(target); 
 
 

Please share the suggestions and Thanks in Advance.
