Hi Matt -- it looks like the documentation is out of data. matplotlib
can now be built to support Numeric and numarray simultaneously, and
which one you are using is controlled at runtime by the numerix
setting in your rc file. The windows installers now have support for
both Numeric and numarray built in.
I recommend you use the matplotlib.numerix module to import your
Numeric/numarray symbols in matplotlib scripts, rather than using
Numeric/numarray directly. The reason is that it is still important
that the arrays you create match the type in your rc file, and the
numerix module insures that this happens.
One good way to do this is
import matplotlib.numerix as nx
a = nx.array(blah)
The matplotlib numerix package structure mirros numarray. Eg to
import mean, you would do
from matplotlib.numerix.mlab import mean
which in numarray is located in numarray.mlab and in Numeric is in
MLab.
If trying to figure out where all the various numerix functions live
makes your head hurt, you can use the pylab module which aggregates
all the numerix and plotting functions into a single namespace
import pylab as p
a = p.array([1,2,3])
n = p.randn(10000)
mu, sigma = p.mean(n), p.std(n)
p.hist(n, 1000)
p.show()
Hope this helps,
JDH
