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

Question

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.

Answer 1

For whoever encounters the same problem, I found a partial solution.

The bidi package provides this functionality, so using:

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

displays it correctly.

So why is it partial? Because I found out that the bidi package sometimes messes up latex expression which I use with matplotlib. So use it carefully.
