Sorry everyone, I found the problem. I had earlier written SetOptions[Plot,......] in another window. I was trying things out in another window and I completely forgot about that setting. The Plot options that I set earlier were causing the problem below. Once I realized this, and restarted the kernel, now I can see that ImageSize->Full works as expected. So, please ignore everything I said below. Just a user error. I have to be carful from now on with the use of SetOptions. Since we are on the subject, I could not find a way to reset options back to default. One way I do it now is default=Options[Plot]; <---- do this initially. (may be in init.m) SetOptions[Plot,..new options...]; now to go back, I do SetOptions[Plot,default] But It would be really nice if there is a way to say SetOptions[Plot, DefaultOptions ] or a new command called ResetOptions[Plot]; without having to do the above or to restart the kernel. or something like this. --Nasser "Nasser M.
