script for redoing a large number of plots?

#1

Hi,

for my thesis I have a laaaaarge number of plots generated
by--again--a laaaaaaarge number of Python scripts.

Now I need a moderate font size for all of them for the thesis while
for a presentation and poster it needs to be much bigger.

In order to keep track of all the plots and files I use a script which
just calls them and copies the relevant files to a folder:

import pylab, shutil, subprocess

cwd = os.getcwd()
dest = './pyplots/'

p20 = '../20_Glasses+Liquids/'
p21 = '../21_LensDesign/'
p22 = '../22_comsol/'
p23 = '../23_OSLO/'
p23_glc = '../23_OSLO/OSLO_glc/'

def main():
  runP20()

def runP20():
  os.chdir(p20)
  subprocess.call([sys.executable, 'Generic_OpticalLiquids.py'])
  os.chdir(cwd)
  shutil.copy(p20+'Generic_OpticalLiquids_n-V.pdf', dest)

This might be a very clumsy approach but I find it very helpful. The
problem is that changing any rcParam has no effect on the created
files, opposed to using execfile instead of subprocess.call().

What can I do to change plot settings globally for that task?

Thanks in advance,
Daniel

If I understand correctly what you are trying to do, you need to set your rcParams in a matplotlibrc file that will be the one found for a given run through all your scripts; or modify your scripts so that they take rcParams on the command line, and modify your master run-all script so that it feeds those rcParams to each script as it is called.

For the first approach, you can either have your master script copy a given matplotlibrc file into each subdirectory before doing your chdir() to that subdirectory, or you can simply set that matplotlibrc file at the beginning of the run, using a single location on the search path for matplotlibrc. That search path includes a path that you may set using the environment variable MATPLOTLIBRC, and, relative to your home directory, ".matplotlib/". For either type of path, note that it is a directory that is specified; the file is always named "matplotlibrc".
