Matplotlib should be a Monoid

[fhaust]

This makes it possible to use mconcat and co to combine graphs:

main = do
    onscreen $ mconcat [ axvline x | x <- [1..10] ]

axvline x = mp # "plot.axvline(" # x ## ")"

Good idea!

Btw... My initial reflex was to tread `Matplotlib` like a Monad... I guess that's possible two, but I did not look into it further. Am 30.05.2017 5:33 nachm. schrieb "Andrei Barbu" <notifications@github.com>:

The very first version actually had it as a monad. But after using it for a bit I realized that it doesn't really do anything useful as one. I at least don't compose graphs while another computation is running (but maybe others are interested in this?). And I can't really see how it would be useful as a monad transformer.

Maybe if the graph wasn't static this would make much more sense? But even then the monad wouldn't really have any interesting laws or behavior aside from passing the graph around in the background. Can you think of any interesting any monad laws or non-trivial bind for this?

Not really... That was just for something like: forM list $ \x -> axvline x Can be realized with Monoid just fine Am 30.05.2017 6:00 nachm. schrieb "Andrei Barbu" <notifications@github.com>:
