Is uicontextmenu working for R2020a? // Answer: NO. Use R2019b instead.

Hi all,

So I have this function to zoom and pan the plot by clicking the right mouse button.

function zoom_pan
hCM = uicontextmenu; 
hMenu = uimenu('Parent',hCM,'Label','Switch to zoom',...
        'Callback','zoom(gcbf,''on'')'); 
hPan = pan(gcf); 
hPan.UIContextMenu = hCM; 
pan('on')
hCMZ = uicontextmenu;
hZMenu = uimenu('Parent',hCMZ,'Label','Switch to pan',...
'Callback','pan(gcbf,''on'')');
hZoom = zoom(gcf);
hZoom.UIContextMenu = hCMZ;
zoom('on')

end

The function allows me to switch between zoom and pan.

Yesterday, this function worked. But suddenly today is not working.

In this order, the default function is zoom-in. However, I cannot switch to pan function.

If I reverse the order, I can switch from pan to zoom, but I cannot go back to pan. This function was amazing for this purpose. Pan and zoom really fast and always available but clicking the right mouse button.

Do you know if the is some update regarding this uicontextmenu with R2020a?

Unbelievably, R2020a does not support uicontextmenu function anymore. I have to use R2019b instead.

Thanks MatLab "support" for wasting my morning trying to fix my scripts when they are working excellently.

I am wondering how can I migrate all my scripts to Python.

When I run your code in R2020b, I get the expected result: a right-click context menu that allows me to switch back and forth between pan and zoom.

figure(1),clf(1),plot(rand(10,2))
zoom_pan % works as expected

I has the exact same behavior on R2018a, so I don't see what you mean. Are you getting any error?

uicontextmenu always works, up to R2020b, on standard figure/axes. You might experience different on uifigure, uiaxes.

Also pay attention if the uicontextmenu is not shadowed by other graphic objects that are plots on the same container.
