Algorithm to draw a dotted line that joins two shapes!

Hi,

I need to draw a dotted line to join two shapes - triangle and circle that are rendered in the chart with two different (CategoryDataSet) datasets.

Do I need to draw a line chart on top of the original plot or I need to use my own algorithm? ....
Any JfreeChart API can help in this regard?

Any pointers here will be greatly appreciated.

Thanks,
SNK

Perhaps you can use the CategoryLineAnnotation class?

Thanks. That helps. Can I use that to draw a Vertical Annotation, say, for intsance, to draw an annotation to represent the current date when the domain axis(X-axis) represents DateAxis?

Thanks,
