I cannot find the method for adding an toolbar with function of zoom in/out in the app designer, if it is not been supported now?

Is there any option to just apply the zoom option to one of the two axis? Thank you very much in advance.
Best regards, Blanca

Zooming and panning was supported in MATLAB R2017a but you had to turn those interaction on.
Starting in R2018b, those interations were on by default.
Starting in R2019a those interactions became available in the toolbar.
For more details, Here is a guide on zooming and panning UIAxes in App Designer for various Matlab releases.

You can try this:

               pan(app.UIAxes,'on');
               zoom(app.UIAxes,'on');

Then create a button to get the zoom 'off' and reset the axis:

                 zoom(app.UIAxes,'off');
                 app.UIAxes.XLimMode = 'auto';
                 app.UIAxes.YLimMode = 'auto';

Can you provide an example code in app designer with the callbacks?

Sure. In standard matlab I can do this:
figure
plot(1:10)
drawnow
zoom(gca,'on') %start zoom mode
keyboard
%click, zooms in
zoom(gca,'out') %zooms out
keyboard
%check that figure is zoomed out
zoom(gca,'off') %exit zoom mode
If I have an axes in appdesigner, I can do
zoom(app.UIAxes, 'on')
%now clicking/scrolling in the figure will zoom in
zoom(app.UIAxes, 'off')
but not
>> zoom(app.UIAxes, 'out')
Error using matlab.ui.control.UIAxes/togglemode
Unknown action character vector.

Unfortunately, App Designer does not offer support for adding a toolbar at this time.

Try to build your on zoom ;) Once your figure is ploted, add an edit field (here you should insert the specific area in your figure to where you want to zoom) after add a slider to control the zoom (the slider values should control your Xlim) add a callback to the slider in order to plot the figure again (use the same code you used to plot the figure but now use the edit field and the slider values to control your XLim) everytime you change the slider value your figure will be updated.
Good luck!

Make sure to check if the 'PickableParts' and 'HitTest' are set like in this picture. This solved my problem, hope that it solve yours too.
