Hi,
this is my code after pressing pushbutton:
h=findobj(0,'Type','figure','Tag','figure1');
UserData=get(h,'UserData');
h=figure;
set(gcf, 'units','normalized','outerposition',[0 0 1 1],'name','a','numbertitle','off'); % Maximize figure.
g=plot(t,x);
UserData.d=7;
set(h,'UserData',UserData);
guidata(hObject, handles);
Why I do not have UserData.d=7 in others pushbuttons? Thank you

Because UserData is not defined for other callback functions. That is why you cannot access UserData with other pushbuttons. You can define it global and that will allow this being accessed by other callbacks.

How can I do it?
I always use UserData between callbacks.
