[matplotlib-devel] Neat vector field plots

[Fernando P. <fpe...@gm...>]

Howdy,

just saw this on the sage list:

http://sview01.wiredworkplace.net/pub/vfplot/index.html

The code is partly GPL (it uses a BSD kd-tree library), so don't go
looking there.  But the basic ideas sound pretty neat for producing
very clean-looking vector fields.  It would be neat if mpl grew
something along these lines...

Cheers

And now that we have spline path elements in mpl98, we can actually
implement curved arrows w/o an onerous polygon approximation.

Then could we do this too?

That appears to have a gradient field gray->white on the arrows, which
we haven't implemented.  But I'd like too...

A bit of acid and the right music on top of that figure, and you can
sell MPL for psychedelic raves :)
