This is expected behavior as "PostActionCallback" method is not supported without going into legacy mode. Using custom toolbar is not possible in legacy mode.
The interaction behavior in figures created in R2024b and earlier versions of MATLAB is called "legacy exploration modes". In legacy exploration modes, you can control interaction behavior only on a per figure basis. So, in legacy exploration modes, all the axes inside a given figure always have the same interaction modes. For more information on legacy exploration modes, please refer to the legacy exploration modes documentation.
Instead of using "PostActionCallback", you can follow the below approaches:
- Use "xtickformat" function to update date labels automatically on zooming>> xtickformat(app.UIAxes,'MMM-yyyy');
- You can also use "LimitsChangedFcn" to set a custom callback function. For example: >> app.UIAxes.XAxis.LimitsChangedFcn = @(src,event)updateDateXTicks(app);
