[Matplotlib-users] Matplotlib + py3 + gtk3 wouws

[Jon Roadley-B. <jon...@gm...>]

Good evening,

I am at present migrating an application of mine from py27+pygtk (with mpl)
to py33+pygobject (gtk3)

Unfortunately I am unable to use

from matplotlib.backends.backend_gtk3agg import FigureCanvasGTK3Agg as
FigureCanvasfrom matplotlib.backends.backend_gtk3 import
NavigationToolbar2GTK3 as NavigationToolbar


Which is is on the examples (
http://matplotlib.org/examples/user_interfaces/embedding_in_gtk3_panzoom.html)
but is also the logical translation from what I presently have.
This falls fowl of the cairo issue

What I am having to use is backend_gtk3cairo. However this is being
triggered

 raise ValueError("The Cairo backend can not draw paths longer than 18980
points.")

I am generally plotting 7 x-y plots with upto 30,000 points.
Now for now I have commented this out from my local install, is there a
better/preferred/recommended alternative?
I have read about cairocffi but this doesn't seem conveniently possible at
this moment in time (especially for windows)

Equally I have seen mpl-devel mailing list entries from 4years ago stating
that this check was to be removed (a cairo 1.4.10 issue)
