Enthought - matplotlib (problems with plot() function )

Trying to use matplotlib on Canopy Express, even a simple code does not run..
NOTE: system does not recognize plot(x) function.. It seems there is
something with ASCII X Unicode. My computer uses UNICODE English(US)..

dashes = [10, 5, 100, 5] # 10 points on, 5 off, 100 on, 5 off
