Myself and several of my friends would find it useful to have a
plotting library that we can use from ghci to quickly/easily visualize
data. Especially if that data is part of a simulation we are toying
with. Therefore, this proposal is for: A gnuplot-, matlab- or
plotinum-like plotting API (that uses diagrams as the backend?). The
things to emphasize:
* Easy to install: No gtk2hs requirement. Preferably just pure
haskell code and similar for any dependencies. Must be cross platform.
* Frontend: graphs should be easy to construct; customizability is
not as important
* Backend: options for generating static images are nice, but for
the use case we have in mind also being able to render in a window
from ghci is very valuable. (this could imply something as purely
rendering to JuicyPixels and I could write the rendering code)
I maintain the Chart library:
http://hackage.haskell.org/package/Chart
I'd like to see it used more widely, but gtk/cairo seems to be a problem
for many people.
Is the cairo dependency the reason you are suggesting that an
alternative plotting library be built?
Is your problem with cairo the difficulty in setting it up on ms
windows/osx?
What graphics API would you suggest using to "render in a window from ghci"?
If there were a good cross platform alternative to cairo, I'd happily
target this additional 2D drawing API. However, I don't think there
currently is one. Neither gloss nor the diagrams library currently have
adequate text support.
