Matplotlib + Latex Rendering / twinx（）：次要Y轴上的字体错误？

Question

I am using matplotlib to generate diagrams with text being latex-rendered. Now there's this tricky problem which I don't seem to be able to solve by myself..

The secondary y-axis generated using twinx() shows the wrong font for ticklabels and ylabel! What am I doing wrong? Here is what I do.

    from matplotlib import pyplot as plt
    from matplotlib import rc
    from matplotlib.figure import Figure               
    from matplotlib.axes import Axes    
    from matplotlib.lines import Line2D

    rc('font',**{'family':'serif','sans-serif':['Computer Modern Roman']})
    rc('text', usetex=True)

    fig = plt.figure(figsize = (4,4) )                                
    ax = Axes(fig, [.1,.1,.8,.8])  
    ax_ = ax.twinx()                            
    fig.add_axes(ax)

    fig.add_axes(ax_)       

    l = Line2D([0, 1],[0, 1], color='r')

    ax.set_ylabel(r'Label')
    ax_.set_ylabel(r'Label')

    ax.add_line( l )

    plt.show()

Versions in use: matplotlib 0.99.1.1 tex.. no idea ; all on linux

ps: rendering text, title and so on works fine this way, it is only the secondary y-axis that is behaving rather badly!

Answer 1

The best answer to this may be to update your matplotlib version if it is at all possible. If subsequently you are still getting issues at least it would mean that you could open a bug report on the matplotlib github site (https://github.com/matplotlib/matplotlib/issues/new).

Answer 2

I am maybe a little bit late, but no one as written a good answer yet. I have got the same problem and solved it by writing the ticklabels in latex:

import matplotlib.pyplot as plt
labels = [r"$1.$", r"$1.5$", r"$2.$"]
ticks = [1., 1.5, 2.]
plt.set_xticks(ticks)
plt.set_xticklabels(labels)
