I like the command structure of your program. Unfortunatly I cannot 
create a plot with it. The plot command fails:
-----------
oscopy> plot
Traceback (most recent call last):
  File "./oscopy", line 50, in <module>
    eval("cmds." + cmd + "(args)")
  File "<string>", line 1, in <module>

I'm using 
  matplotlib 0.98.5.2
  python-tk 2.5.2
  OS: openSUSE 11.0
