Solve : Zoom in/out for java graph.?

1.	Solve : Zoom in/out for java graph.?
Answer» I have generated a GRAPH using java, but WITHOUT using any external packages like jfreechart etc. Now is it possible to add a zoom in/out feature, with or without using external packages? And how? I have GOOGLED a lot but not getting anything. Simple graph using only java NOTHING special in that. Just how do I add a zoom in/out feature to it.
