Representing data in terminal mode

Hi,

I use matlab on Linux and I like to run it from shell as:

~$ matlab -nodisplay -nosplash

it is a little bit faster (I think it could be even more faster ..), however, seems the plot, stem, and maybe other graphing functions don't work while using matlab in terminal mode. Am I doing something wrong or maybe this is a problem of matlab software ?

Thank you in advance.
