I am not certain but I think that matplotlib includes some C code and so it won't work on GAE. But the new module can easily be extended with other backends like Google Chart API.
Also there are some less used matplotlib backends that do not need compilation (pure python) http://old.nabble.com/Pure-python-matplotlib-for-Google-App-Engine-td32721389.html > >> >> 5)Ipython like notebook. >> I think it is possible to port the Ipython notebook according to this >> discussion(https://groups.google.com/forum/?fromgroups#!topic/sage-notebook/re2bUt4vCxA). >> But the time it takes to port is not very fixed.
