Join a rectangle annotation with another annotation in JFreeChart?

Question

I have used XYAnnotation and drawn a rectangle in xylinechart. Now how can I join it with another rectangle annonation?

Answer 1

One way would be to use an XYLineAnnotation

plot.addAnnotation(new XYBoxAnnotation( 0.5,0.5,1.5,1.5));
plot.addAnnotation(new XYBoxAnnotation( 4.5,3.5,5.5,4.5));
plot.addAnnotation(new XYLineAnnotation( 1.5,1.5,4.5,3.5));
