在matplotlibrc中设置破折号样式

Question

Can I define the dash style, ie length and separation, in the matplotlibrc file?

Right now, I have to do something like this:

plt.plot(x, y, '--', dashes=(3,1))

I want to put the option "dashes=(3,1)" into the matplotlibrc, but could not find anything about it.

Thanks

EDIT: For clarification: I don't want to set this globally, but for a stylesheet ( http://matplotlib.org/users/style_sheets.html ), where the default dash style is too coarse, because the style is for small images for a publication.

If you really need to reuse this particular style a lot, you can simply create a partial function that sets a default for dashes= parameter.

import functools
dashed_plot = functools.partial(plt.plot, dashes=(3, 1))

(It's not necessary to specify linestyle= when using the dashes keyword parameter).

The rcfile is for other things such as what rendering backend to use, that should be set globally. I wonder why you want to enforce a dash style for everything as an rc option.
