Special characters in plot

[pomxipum]

fig1=plt.figure() ax1=fig1.gca() im1=ax1.imshow(tab_amp,cmap=cm.rainbow,extent=(0,90,-45,45),interpolation='bilinear') ax1.set_xlabel(u'\u03b8 (°)') ax1.set_ylabel(u'\u03c6 (°)') cb1=fig1.colorbar(im1) cb1.set_label(u'Amplitude de \u03b8ij (°)') cs1 = ax1.contour(tab_amp_inv,colors='k',extent=(0,90,-45,45)) ax1.clabel(cs1, inline=1, fontsize=10,color='k')

I worked before then I installed prettyplotlib and now I gives this

I think prettyplotlib has changed the default font in python to a font that doesn't allow unicode character. How can I changed it back?

Sorry about your issue. I'm not sure what could be causing it. Can you find out your python, matplotlib, and prettyplotlib versions? Python 3 is supposed to have better unicode support but I haven't fully made the switch.

I used this code and got similar errors:

import matplotlib.pyplot as plt
from matplotlib import cm

fig1=plt.figure()
ax1=fig1.gca()
im1=ax1.imshow(np.random.normal(100, size=(10,10)),cmap=cm.rainbow,extent=(0,90,-45,45),interpolation='bilinear')
ax1.set_xlabel(u'\u03b8 (°)')
ax1.set_ylabel(u'\u03c6 (°)')
cb1=fig1.colorbar(im1)
cb1.set_label(u'Amplitude de \u03b8 ij (°)')

Are these the same imports as you? Can you also do pip list to show all the packages you have installed?

[pomxipum]

Yes, I've the same imports. I use Python 2.7.3 pip list doesn't work for me but I've just install mplotlib and prettyplotlib for about 1 month so I think they're the newest versions.

Thank you for your comment. Unfortunately, I no longer have the bandwidth to maintain prettyplotlib. I recommend using seaborn. Using seaborn, to get the prettyplotlib style, do:

import seaborn as sns
sns.set(style='ticks', palette='Set2')

And to remove "chartjunk", do:

sns.despine()

If you have discrete pull requests, I will accept them, but I personally will no longer fix bugs.
