Auto rescale axis on range change (x/yaxis.min/max)

[Michael Wieland]

I'm trying to auto rescale my chart once I select a range using the mouse.

The Y axis should be recalculated automatically based on the displayed range.

If you select a range where the Y axis data is between 0 and 40 the axis should scale to that range instead of keeping the full range.
