Latest Matplotlib with GR as a backend?

[lsolanka]

Hello there,

I'm trying the matplotlib backend example with the latest matplotlib (3.3.3): https://gr-framework.org/tutorials/matplotlib.html

I'm taking this code:

import numpy as np
import matplotlib.pyplot as plt
t = np.arange(0.0, 2.0, 0.01)
s = np.sin(2*np.pi*t)

plt.plot(t,s)
plt.title(r'$\alpha_i > \beta_i$', fontsize=20)
plt.text(1, -0.6, r'$\sum_{i=0}^\infty x_i$', fontsize=20)
plt.text(0.6, 0.6, r'$\mathcal{A}\mathrm{sin}(2 \omega t)$',
         fontsize=20)
plt.xlabel('time (s)')
plt.ylabel('volts (mV)')
plt.show()

Then setting the backend through the environment variable: export MPLBACKEND="module://gr.matplotlib.backend_gr", and running the example script, simply does not produce any window.

Anything I'm missing here?

I cannot reproduce this problem:

export MPLBACKEND="module://gr.matplotlib.backend_gr"
python3 -i your-example-script.py
