Why do you think it is not needed?

A DrawingArea does not keep track of its contents, every expose happens from 
the ground up. That's 
why you lost your previous plotted points.

In that way, handling eg another window on top of yours, minimizing and opening 
again of the app, or 
moving the app to another desktop will all work as expected.
