how to set gui axes ylim

i created a axes object in gui and set ylim[-1 1] in property inspector,but the figure will be showed this

and i try to change parameter about ylim value form matlab program,but it just add one more new axes

what sould i solve this problem?and i couldn't find the function about axes in matlab program.should i creat a function for setting axes property?

[mr. wang]

    axes('Parent',controller,...
        'HandleVisibility','callback',...  
         'OuterPosition',[0.25 0.1 0.75 0.8],...
        'Xlim',[0 10],...
        'YLim',[-1 1],...
        'Tag','axes1');

i put this program in slider callback function just for test the axes will be changed property or not

This command:

 axes('Parent',controller,...);

will create new axes, because that is what it is supposed to do.

If you want to change the properties of existing axes, then you need to access its properties using set and get, or for newer MATLAB versions using dot notation:
