OO style matplotlib?

First, WOW! I love Pythonista already! Thank you to creators and contributors!
I am using matplotlib and prefer to use the OO style of coding as described <a href="http://matplotlib.org/1.3.1/faq/usage_faq.html">here</a>. In other Python environments, I have no difficulty doing this, but in Pythonista the script
import matplotlib.pyplot as plt fig, ax = plt.subplots(1, 1) ax.plot(1, 1, 'ro') fig.show()
produces the error "UserWarning: matplotlib is currently using a non-GUI backend, so cannot show the figure."
I tried adding
plt.ioff()to the script, since Pythonista documentation does warn that matplotlib GUIs will not implement interactive behavior, but it still does not produce the plot. I am able to produce the expected plot using
plt.plot(1, 1, 'ro'). The <a href="http://omz-software.com/pythonista/docs/matplotlib/faq/usage_faq.html"> Pythonista mirror of matplotlib's documentation </a> seems to suggest I can use the OO style to code with matplotlib.
Is it possible to use the OO interface to matplotlib with Pythonista? If so, how?

Thanks for the feedback. You can work around this limitation by saving the plot to an image first, and showing that (the non-OO
show()does pretty much the same internally):
import matplotlib.pyplot as plt import Image fig, ax = plt.subplots(1, 1) ax.plot(1, 1, 'ro') fig.savefig('mpl_out.png') Image.open('mpl_out.png').show()
