I want to turn axis for my both axes. But the following code work only for axes 2. Can anyone tell why is it so?

% if true
% code
% end
function pushbutton1_Callback(hObject, eventdata, handles)
y1=randn(40);
handles.y1=y1;
y2=randn(40);
handles.y2=y2;
guidata(hObject, handles);
function pushbutton2_Callback(hObject, eventdata, handles)
y1=handles.y1;
y2=handles.y2;
imagesc(y1,'parent',handles.axes2)
axis off
imagesc(y2,'parent',handles.axes1)
axis off

axis off
Operates on the "current axes" (that returned by the gca function). Nowhere in your code do you set (change) the active axes, running axis off twice produces redundant results.
As with your calls to imagesc(), supply the axes handle explicitly in your calls to axis().
