Re: [Matplotlib-users] python question from matlab user

Hi all,

Thats what I thought too:

I have: jmkfigure.py:

===============
from pylab import *

def jmkfigure():
    rc('figure',figsize=(3+3/8,8.5/2),dpi=96)
    rc('font',size=9);
===========

and test.py:

=========
from pylab import *

from jmkfigure import *

jmkfigure()
figure(1)
plot([1,2,3]);

show()
==============

>>> run test.py

yields a traceback ending w/:

===========
Users/jklymak/teaching/Phy411/project/jmkfigure.py in jmkfigure()
      1 from pylab import *
----> 2 
      3 def jmkfigure():
      4     rc('figure',figsize=(3+3/8,8.5/2),dpi=96)
      5     rc('font',size=9);

NameError: global name 'rc' is not defined
========

Same error if I just import "rc" from matplot lib....

Is it some strange set up problem?  If I put the same def in test.py it works fine...

Thanks,  Jody
