Java real time plotting with visualvm

Hi there,

I have manage to use successfully the visualvm for real time plotting with java. Now I am trying to achieve something more with it but I cant find it if is supported or how to do it.

So what I want to do is draw at my real time plot, some 2D Graphics like rectangle and etc. A thing like jfreechart has, if someone knows. In jfreechart is called XYAnnotations.

So I search a nit the source code from visualvm charts but I dont understand if is possible to do it or not?

So any guidance on how to do it would be great.

Regards,

Nick
