Matplotlib

Haskell bindings to Python's Matplotlib. It's high time that Haskell had a fully-fledged plotting library!

Documentation is available on Hackage. For more examples see the tests.

{-# LANGUAGE ExtendedDefaultRules #-}
import Matplotlib

onscreen $ contourF (\a b -> sin (degreesRadians a) + cos (degreesRadians b)) (-100) 100 (-200) 200 10

We need -XExtendedDefaultRules to avoid having to manually having to specify certain types.

Installation

You will need several python libraries to run this code which can be installed on Ubuntu machines with the following command:

sudo apt-get install -y python3-pip python3-matplotlib python3-numpy python-mpltoolkits.basemap

If you have instructions for other machines or OSes let me know. We require /usr/bin/python3 to be available; the path isn't configurable right now.

Once you have the prerequisites you can install using the standard incantation

cabal install matplotlib
