Interesting. As it turns out, on XP numpy is in Add/Remove, so it can be
removed there. Should be a problem.

Switching

I'm working in IDLE in Win7. It seems to me MPL gets stuck in
site-packages under C:\Python25. Maybe this is as simple as deleting the
entry?
Well, yes there's a MPL folder under site-packages and an info MPL file
of 540 bytes. There are also pylab.py, pyc,and py0 files under site.
I was just looking at the (Win) Python documentation via the Help on
IDLE, and a Global Module Index. Does anything like that exist for
numpy, matplotlib, scipy?

Will that eliminate the need for T?
I'll go back to Tenative Python, and re-read dimension, shape and the like.

I've all too often had to write my own histogram programs for this,
FORTRAN, etc. My data is from a 640x480 collection of b/w pixels, which
a processor has binned from 0-255, so I don't want repeat doing a
histogram on 307K data points.

The histogram x-axis goes from 0 to 4.5. How does that happen?
