Re: [Matplotlib-users] savefig problems with matplotlib

[James L. <jwl...@gm...>]

I tried using tkagg by setting

backend  : TkAgg

in my matplotlibrc, which includes only the following lines:

backend         : TkAgg

# latex options for matplotlib

font.latex.package    : type1cm
text.usetex        : False
text.tex.engine        : latex

I get the following message, when I try to use it, which I don't understand=
,
because I have tkinter installed:

[jwlandry@merrimac flow]$ ~/grain/plots/hopper/pof-w-insert.py data_hopper-
40k-r1.5.funnel-pof.combo data_hopper-40k-r2.funnel-pof.combo data_hopper-
