Mupad: using Object Browser to change axis limits

Please help urgently! I am using Mupad in my teaching and in the notes we are using it is advised to use Object Browser to change appearance of plots (we move on to using command options later on in the course).

However, I cannot figure out how to change plot axes limits using Object browser! Changing VewingBoxXMin etc parameters does not do anything to the plot at all! I have played with Constrained/Unconstrained box options and all it does is shrink the plot to specified limits which is not what I am after.

There must be something I am missing, please tell me how to do this properly.
