Hi, modellers,

I installed both "python-matplotlib" and "gnuplot" on my Fedora 13. My system have three versions of python:

python2.6: /usr/lib/python2.6/

python2.3: /usr/local/lib/python2.3

python2.7 /usr/local/lib/python2.7

matplotlib is under python2.6 /usr/lib/python2.6/site-packages/matplotlib

#################### the command "mod9.9 plot_profile.py" gives the following error:

Traceback (most recent call last): File "plot_profiles.py", line 1, in ? import pylab ImportError: No module named pylab ##################### the command 'gnuplot "TvLDH.profile" using 1:42 with lines' gives this error:

How to fix my system to make the gnuplot and matplotlib work?

Thank you.
