[Scilab-users] Redrawing a maximized figure changes its original size and other problem

[Federico Miyara]

Philipp,

No, I don't want to have the figure maximized always; rather, to be able 
to toggle between normal size and maximized (when I need to focus on 
small details such as the difference between experimental and fitted 
graphs). That's actually why the current behavior is bothersome, since 
once redrawn, there is practically no difference between normal and 
maximized, so I cannot, for instance, see at the same time two figures. 
I need then to resize it manually. I shouldn't need to tweak the figure 
properties for that...

As to question 2, I refer to the normal location immediately after 
rendering the figure. The botton of the figure is hidden by the task bar 
so I find myself having to manually relocate each and all figures I 
create just to see its complete content, and that doesn't seem to be a 
normal or expected behavior.

I don't know if that happens only to me or everyone is experiencing this 
when the task bar is always visible.

Regards,

Federico Miyara
