I have a plot and I want the user to not be able to change the Y axis. Is it possible?
Is there a call back option to the Zoom In/Out tool function?

This is the solution:
ZoomHandle = zoom(h.Figure(1))
set(ZoomHandle,'Motion','horizontal')
Thanks to all that helped!

I tried both
zoom yon
and
ZoomHandle = zoom(h.Figure(1))
set(ZoomHandle,'Motion','horizontal')
it worked on live fig, but when fig is stored as .fig and re-opened, it still zooms in both direction when clicking zoom+ button.
Did you solve this problem?

Yes, there is a zoom button in the figure's toolbar.
The zoom command is an option also, e.g.:
zoom yon
another idea is to set the axes 's 'YLim' property directly.

But when I press the Zoom button and mark my zoom area on the figure - the X and the Y axes change.
I want to be able to keep the Y axis const.

I noticed that under the tab of 'Tools' there is an 'Options' item.
There I can select that the Zoom will be a 'Horizontal Zoom'.
Is it possible to have that by default when the Plot is opened?
