However, if instead of zooming in/out with the zoom spin boxes you use the mouse wheel, then the graphs try to preserve the position at which the cursor is when you move the wheel. With the graph at 1:1, place the mouse near the bottom left corner and move the wheel towards you. This will zoom in and the graph's position won't change.
That's how I usually do it - unless I want to zoom in/out only in one axis - and not only it works like a charm but it's also very convenient (of course you need a mouse with a wheel
)
But yeah I second the suggestion of anchoring at 0,0 when zooming in from 1:1 using the spin boxes.
