Use of SizeChangedFcn for altering labels

I have created a function (attached fixticks.m) which I often find more convenient than using xtickformat as it is more dynamic in it's behaviour whe zooming in/out.

The use of the zoom properties 'ActionPreCallback' and 'ActionPostCallback' I find very neet in order to keep the automatic ticks when zooming in and out and reapplying the automatic formatting.

BUT - when resizing the figure I often realize that I have to manually zoom in / zoom out before the ticks are correct.

Is there a way to handle this using the SizeChangedFcn or some other property/callback.

It is not my intent to use the functions in a gui or app.
