Python – Matplotlib: Writing right-to-left text (Hebrew, Arabic, etc.)

hebrewmatplotlibpythonright-to-left

I'm trying to add some text to my plot which is RTL (in this case, Hebrew). After some work managed to get it to display the text, but it's displayed LTR (meaning, in the reverese order). I've dug into the reference and did extensive search online and nothing came up.

An example for what I'm using:

import matplotlib.pyplot as plt
plt.text(0.5, 0.5, u'שלום כיתה א', name = 'Arial')
plt.show()

and it displays 'א התיכ םלוש'.
In case you can't see the Hebrew, it's as if i'd input 'Hello', and the output would be 'olleH'.

I can't simply reverse the input since it's mixed LTR and RTL.

Every help would be appreciated.

For Arabic you need both bidi.algorithm.get_display and arabic_reshaper modules:

from bidi.algorithm import get_display
import matplotlib.pyplot as plt
import arabic_reshaper

reshaped_text = arabic_reshaper.reshape(u'لغةٌ عربيّة')
artext = get_display(reshaped_text)

plt.text(0.25, 0.45, artext , name = 'Times New Roman',fontsize=50)
plt.show()

python matplotlib arabic text

Python – Hiding axis text in matplotlib plots

Instead of hiding each element, you can hide the whole axis:

frame1.axes.get_xaxis().set_visible(False)
frame1.axes.get_yaxis().set_visible(False)

Or, you can set the ticks to an empty list:

frame1.axes.get_xaxis().set_ticks([])
frame1.axes.get_yaxis().set_ticks([])

In this second option, you can still use plt.xlabel() and plt.ylabel() to add labels to the axes.

Python – Reduce left and right margins in matplotlib plot

One way to automatically do this is the bbox_inches='tight' kwarg to plt.savefig.

E.g.

import matplotlib.pyplot as plt
import numpy as np
data = np.arange(3000).reshape((100,30))
plt.imshow(data)
plt.savefig('test.png', bbox_inches='tight')

Another way is to use fig.tight_layout()

import matplotlib.pyplot as plt
import numpy as np

xs = np.linspace(0, 1, 20); ys = np.sin(xs)

fig = plt.figure()
axes = fig.add_subplot(1,1,1)
axes.plot(xs, ys)

# This should be called after all axes have been added
fig.tight_layout()
fig.savefig('test.png')
