plot axis and legend without anti-aliased lines

Community matplotlib-users

This code:

···

========================================
import matplotlib.pyplot as plt

plt.plot([1,2,5,3,4], label='line')
plt.legend()
plt.show()

shows this image: http://i.imgur.com/KMPywSp.png

I want axis and legend box with 1px line, like this:

turning anti-aliasing off for all plot lines, which is not what I
want.

Is this anyhow possible?

You need to thin out the default line widths in your matplotlibrc file.

Something like:
import matplotlib

matplotlib.rcParams[‘axes.linewidth’] = 0.5

matplotlib.rcParams[‘lines.linewidth’] = 0.5

…if you don’t want to edit your matplotlibrc file.

Hope that helps,

Thanks Paul, that solved the problem.

    matplotlib.rcParams['axes.linewidth'] = 0.5
    matplotlib.rcParams['patch.linewidth'] = 0.5

is what I wanted and I'll put that in matplotlibrc.

Previously I thought that this is related to some anti-aliasing
setting that would affect all lines drawn. But as it is possible to
set this preference to custom plot elements, this is what I would
always prefer. Default setting looks too blurry for horizontal and
vertical lines.

Cheers
