Displaying a Unicode character

Specify a font with Cyrillic characters. For example,

import matplotlib as mpl
mpl.rcParams['font.family'] = 'Arial'

      

        
        
        
      

    

Your default font might be 'Helvetica'

that doesn't have the glyphs for the required characters.

import matplotlib.pyplot as plt
from numpy.random import normal
from itertools import count
import matplotlib as mpl
mpl.rcParams['font.family'] = 'Arial'
a = {u'\u043f\u0430\u0440\u0435\u0430\u0442\u0430': 0.018144370928201092, u'\u0440\u0435\u043b\u0430\u0442\u0438\u0432\u0438\u0442\u0438\u0441\u0442\u0438\u0447\u043a\u0430\u0442\u0430': 0.008406336989671147, u'\u043d\u0430\u043e\u0453\u0430': 0.0704839024518581, u'\u0444\u0438\u0437\u0438\u043a\u0430': 0.025219010969013446, u'\u043a\u043e\u0438': 0.0039908251856718025, u'\u0438\u0437\u0431\u0443\u0432\u043d\u0430\u043b\u0430': 0.0035792606713834184, u'\u043c\u0435\u0445\u0430\u043d\u0438\u043a\u0430\u0442\u0430': 0.008406336989671147, u'\u043c\u0438\u043a\u0440\u043e\u0434\u0438\u043c\u0435\u043d\u0437\u0438\u0438': 0.008406336989671147, u'\u0434\u0430\u0432\u0430': 0.016812673979342295, u'\u0441\u0442\u0440\u0430\u043d\u0430': 0.008406336989671147}

plt.bar(*zip(*zip(count(), a.values())))
plt.title("Gaussian Histogram")
plt.xticks(*zip(*zip(count(0.4), a.keys())))
plt.xlabel("Value")
plt.ylabel("Frequency")

plt.show()

      

        
        
        
      

    

If you don't have a font Arial

, you can create a list of font files known to your system with

import matplotlib.font_manager as font_manager
print(sorted(font_manager.findSystemFonts()))

      

        
        
        
      

    

Then you can try fonts using

prop = font_manager.FontProperties(fname=path)
mpl.rcParams['font.family'] = prop.get_name()

      

        
        
        
      

    

where path

is one of the paths returned findSystemFonts()

.
