Ok, i found it. It goes as follows..

Code: Select all

           //.... find origin

           x = plot.getRangeAxisEdge().coordinate(dataArea, RectangleEdge.LEFT);

           y = plot.getRangeAxisEdge().coordinate(dataArea, RectangleEdge.BOTTOM);

          //..use origin

Or if someone has a better way to do it, plz post it here. Thanx.

You may also want to consider these two methods in ChartPanel:

translateJava2DToScreen(java.awt.geom.Point2D java2DPoint)
translateScreenToJava2D(java.awt.Point screenPoint)

Thanx Daniel, but use of these methods requires a 'Point2D' and 'Point' instance, which i don't know how to construct at that point of time. I have a Plot instance, a Rectangle2D instance and ValueAxis and DomainAxis instances.
