Hi All,
I have what I think is a basic question. I want to have an
interactive python script/code which uses matplotlib. For example,
the script first asks what data set to use, then when received, it
does some analysis routines, and then makes some plots. To launch the
plot, my I have
for input. Is
this possible to do (in either Python or iPython)?
Thanks,

Hi All,
I am trying to understand exactly what the -pylab option does when I
launch ipython -pylab - thought some folks here might know.
For example, after executing
ipython -pylab
I can type either
a = np.array([1.,10.])
OR
b = array([1.,10.])
are these both numpy arrays? And clearly, t

I'll look into it.
Do you have an idea where I can find a description of the keyword

'%.3f' is nice, but still not scientific format...
you can use

Hi Chris,
I think I understand what you are asking. I think the key point is I have used
"np.histogram" where you are using "np.hist"
When I make my plots, I use np.hist, but then to access the data, I use
np.histogram.

Hi Sean,
I just checked - the hyphenation you want does not work in LaTeX in math mode.
Try removing the "$"-signs in your string command. Then the hyphenation should
work.

Hi All,
I recently upgraded my python packages through Enthought.
I have a mac osx 10.6.8
Previous versions: python 2.6, matplotlib 0.99.3 (Enthought 6.2)
New versions: python 2.7, matplotlib 1.0.1 (Enthought 7.1)
I am using the macosx backend.
I have some functions I wrote which analyze data.
