Any idea how easy it will be to use matplotlib with scipy_core (rather
than Numeric and numarray)? Will it just be a matter of replacing the
import statements?

Chris

Is it possible to build matpoltlib with scipy_core support, rather
than Numeric or numarray? I did what I thought was a successful build
and install, but a quick test resulted in some Tkinter backend errors:

I am trying to compile matplotlib with scipy_core (latest release),
rather than Numeric or nunmarray. However, I get the following error
when trying to build:

Traceback (most recent call last):
  File "setup.py", line 110, in ?
    raise RuntimeError("You must install Numeric, numarray, or both to
build matplotlib")
RuntimeError: You must install Numeric, numarray, or both to build matplotl=
ib

Is there no way to base matplotlib on scipy_core?

Thanks,

Chris, are you using Daishi's patches?  I'm not quite sure if they're in CVS 
yet, but it's certain that you can NOT build mpl 0.85 + scipy_core without them.

Cheers,

Best to hold off for a little while.  The patch was committed to CVS, 
but turned out to have a major problem, so John is working on it.

At the moment it looks trivial.  I have matplotlib 0.84 and "new scipy" 
installed and did:

ipython -pylab
import scipy as S
x=S.arange(10)
plot(x,x**2)

and got a plot.
