Hi there,
I would like to use cairo in order to plot some graph from igraph, but it
somehow doesn't work.
I work on OSX version 10.9.3.
X-code is installed
I usually work on IDLE which version is 2.7.8
I installed igraph
Then I installed Macports and followed a tutorial in order to install
py27-cairo, which installed by the way the following modules :
bzip2 @1.0.6_0 (active)
cairo @1.12.16_2+x11 (active)
db46 @4.6.21_9 (active)
db_select @0.1_2 (active)
expat @2.1.0_0 (active)
fontconfig @2.11.1_0 (active)
freetype @2.5.3_1 (active)

xz @5.0.5_0 (active)
zlib @1.2.8_0 (active)
I can import igraph and use some of its characteristics (like create a
graph) but when I try to plot it, I got the "plotting not available" error,
as follow :
>>> from igraph import *
>>> g = Graph.Famous("petersen")
>>> plot(g)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Library/Python/2.7/site-packages/igraph/drawing/__init__.py", line
458, in plot
result = Plot(target, bbox, background="white")
File "/Library/Python/2.7/site-packages/igraph/drawing/__init__.py", line
129, in __init__
self._surface_was_created = not isinstance(target, cairo.Surface)
File "/Library/Python/2.7/site-packages/igraph/drawing/utils.py", line
396, in __getattr__
raise TypeError("plotting not available")
TypeError: plotting not available
Being new to this world, I absolutely don't know what I did wrong.
I tried to import the modules too, but it doesn't seem to recognize them.
>>> import cairo
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named cairo
Does someone know what I can do to resolve this ? Thank you in advance for
your help !
Cordially,
Floriane
