Gurus,

Windows XP, matplotlib 1.1.0. Backend Tk, but the same elsewhere.

Programme:

import matplotlib as mpl
import matplotlib.pyplot as plt
mpl.rcParams['lines.linewidth'] = 2
mpl.rcParams['lines.color'] = 'r'

x=range(800)
y=[t for t in x]
plt.plot(x,y)
plt.show()

# ==============================
Linewidth OK, equal to 2, but the line is still blue. Changing "r" to 
red, or to #ff0000, or (1,0,0) doesn't change anything, still blue. 
Changing directly the matplotlibrc file (default) - the same. Leaving in 
peace the defaults, constructing another rc in the working dir - the 
same. The dictionary rcParams contains the correct value
'lines.color': 'r'
(Anyway, rcsetup.py validation doesn't protest. But then, the modified 
colour is ignored).

Somebody could confirm that?

The best.
