Hi Tiago,
I am on Ubuntu 16.04 and today I updated from git: '2.23 (commit b669e1b7,
Sun Sep 24 00:01:08 2017 +0200)'.
Till now, I was at least able to draw two graphs in two subplots as said in
my previous email. However, today even that is not working. My code:
import graph_tool.all as gt
import matplotlib.pyplot as plt
plt.switch_backend('cairo')
g1 = gt.collection.data['karate']
g2 = gt.collection.data['dolphins']
ax = plt.subplot(1, 2, 1)
gt.graph_draw(g1, mplfig = ax)
ax = plt.subplot(1, 2, 2)
gt.graph_draw(g2, mplfig = ax)
ax = plt.subplot(2, 2, 3)
plt.savefig('test.pdf')
I get the following error:
Traceback (most recent call last):
File "test.py", line 20, in <module>

323, in _convert
cmap, alpha = cmap
ValueError: not enough values to unpack (expected 2, got 0)
I tried looking into "cairo_darw.py" but couldn't locate the problem. I
think that it might have something to do with the default color map
default_cm but I am not sure about it. Can you kindly help me with this?
Thank you
