I am using 2019b and have not been able to successfully use an evenlistener on the XLim of my axes. I want to listen to changes on the size of the axes but it seems it does not work when the XLimMode = 'auto' altough there is a clear change in XLim. Looking abit more on the issue I found a workaround (https://nl.mathworks.com/matlabcentral/answers/369377-xlim-listener-for-zoom-reset-and-linkaxes-strange-behavior) which I presume does not work anymore in this release.

addlistener(parent_ax,'XLim','PostSet',@ReposFootPrint); % This only works when XLimMode = 'manual'

This alternative using a manual property does not work given that the propety is not SetObservable

addlistener(struct(parent_ax).XAxis,'Limits','PostSet' ,@ReposFootPrint);

Any ideas on how can I use the listener in 'auto' mode?

Thank you

在 MATLAB Online 中打开

Fig 1. Original Placement of footprint @(1,1)

Fig 2. After ploting a new line

plot(parent_ax,[0 2],[0 2])

the listener was not triggered

Fig 3. The callback ReposFootPrint is triggered once the XLim property is manually set, placing back the footprint to its original location (this should be automatic)

In Matlab r2021a and later, see this community highlight for a demonstration of the new LimitsChangedFcn that is easier to use and more reliable than applying a listener to the xlim property. The demo moves a text object any time the axis limits change. That can easily be applied to your footprints.
