[Matplotlib-users] matplotlibrc has no effect on the plot? (windows7)

[mato]

I want to change the look of the default plots in Python, so I created the
file matplotlibrc in the current working directory (Windows 7). The file
gets loaded:

/import matplotlib as mp
print('Config. file loaded from:', mp.matplotlib_fname())/

prints:

/Config. file loaded from:
C:\Users\mato\Documents\Python_Scripts\matplotlibrc/

however, the plot is unaffected.

The simple code:

/import matplotlib.pyplot as plt
x = [1,2,3,4,5]
plt.plot(x)/

with the matplotlibrc file that looks like this:

/lines.linestyle : --
axes.grid : True/

yields the plot with the solid line and no grid in the plot. What am I
missing?

Note:
If I insert

/plt.rcParams['axes.grid']=True
plt.rcParams['lines.linestyle']='--' /

in the code, it works as expected

Are you using IPython QtConsole / Notebook? I think they have their
own settings on their backend.

This might be the case (I'm running Anaconda/Spyder/Ipython) however so far I
haven't been able to locate the appropriate settings file...

Here is what I did:

Put a 00_matplotlib_rc.py in ipython's profile_default/startup folder
(you might need to run ipython profile create, or ipython profile
locate to create/find them), and in the file specify my matplotlib rc
parameters. For example:

import matplotlib as mpl


# Figure formatting
mpl.rcParams['savefig.dpi'] = 300
mpl.rcParams['figure.figsize'] = (3.27, 3.27)

# Font setting
mpl.rcParams['mathtext.default'] = 'regular'
mpl.rcParams['font.family'] = ['sans-serif']
mpl.rcParams['font.sans-serif'] = ['Arial']
mpl.rcParams['font.size'] = 8
mpl.rcParams['pdf.fonttype'] = 42
mpl.rcParams['ps.fonttype'] = 42

# Line properties
mpl.rcParams['lines.linewidth'] = 1.
mpl.rcParams['lines.markersize'] = 4

# Legends
mpl.rcParams['legend.frameon'] = False
mpl.rcParams['legend.fontsize'] = 8
mpl.rcParams['legend.handlelength'] = 3

# Subplot frame line
mpl.rcParams['axes.linewidth'] = .5



I would be happy to know if there's a better/different way to do it.

...or I can put the file(s) that dynamically change the rc settings in the
current directory and just execute them (import) whenever I want to use
different settings for the plots.
This is less elegant than the configuration file, but at least solves my
problem for now.
Thank you Yuxian.

Cheers

Shawn,

This might better be sent to the IPython mailing lists.
