Re: [Matplotlib-users] matplotlib, numpy, numarray

[Eric F. <ef...@ha...>]

Thanks.  There were in fact several points of incompatibility with 
Numeric and numarray. (Normally I would have checked this, but I slipped 
up.) I have changed quiver.py and numerix to solve the immediate 
problem, and to slightly reduce the incidence of such problems in the 
future.  The real solution, of course, will be a complete transition to 
numpy.

Regarding griddata: I downloaded it a few minutes ago, built it, and 
tested it with numpy, and it worked fine, at least with the test.py that 
comes with the package.  Looking very quickly at the code, I don't see 
anything specific to any numeric package; it is using the buffer 
interface at the C level and matplotlib.numerix at the python level. 
Perhaps the author, Jeff Whitaker, can shed more light on this question.
