There is a script called 'plotit', included with the WxMpl library,  
that provides very limited command-line plotting of whitespace- 
delimited ASCII data files, e.g.

        $ plotit '$1' '$3/$2' somedatafile anotherdatafile

There's also support for strip charting data as it arrives from  
stdin, but you have to communicate using an ugly legacy language.   
The script is currently a wxPython-only program that depends on WxMpl  
to embed the plot, but you could probably modify it to work using  
pylab without too much pain and suffering.

The WxMpl source tarball, which includes plotit, can be downloaded from

        http://agni.phys.iit.edu/~kmcivor/wxmpl/

If you just want to start hacking on the script you can pull it  
straight from the subversion repository instead:

        http://svn.csrri.iit.edu/mr-software/wxmpl/trunk/plotit
