Hi Roger

My name is Hakan Nyberg and I've added a matlab type interactive zoom capabilities into your great DataPlot Classes package.

The changes are developed and tested on a winPC, but I think it will work on Mac also.
Use it in future releases if you think its a good feature.

Unpack the project and run it. Activate the zoom command by choosing "zoom on" from the contextual menu in the graph. draw a rectangle around the parts that you want to zoom in on with the left mouse button pressed.

Thanks for a great sw package
