Zooming Out after "Zoom into the graph"

[mythsmith]

The very useful "Zoom into the graph" function changes the axes ranges so that the viewed graph corresponds to the rectangle traced by the user on the graph.
It is not clear how to "go back" from this action: there is no "Zoom out from the graph" button, as far as I could see.
It should be possible to reset all axes ranges to Auto by clicking a simple button, or go back through all the "Zoom into the graph" actions up to any intermediate zooming rectangle.

You can always "undo" to go back to the original graph. A reset to default button when the axis is selected is a nice idea. You can currently zoom out by dragging one set of the black squares which appear when an axis is selected (the others move the ends of the axis).

Thanks! Did not think about the old plain undo action!
My problem with an axis-by-axis operation is that on some graphs I have a huge number of axes (10), so it would be tedious.
Thanks again!
