Can I lock the Y axis (Even when the Zoom In/Out is used)?

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.

[Nimrodb]

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?
