Ahhh... Yes, I should turn to scipy for this. Great suggestion!
I'll look for least square fit and maximum likelihood fit.
My next question is about plotting any function f(x) on top of data.
I know I could just produce enough (x,y) points and plot(x,y).
But a convenience function like plot(f,
Hi All,
I've been compiling svn versions of matplotlib on OSX for quite a while
with no (or few...) problems.
On upgrading to leopard on my mac pro, I've run into the
error messages below.
External libs are from fink. There seems to be some problem with
attempts to build a universal binary.
Great! Glad to hear that's resolved.
Yes -- saving PDF's from the GtkAgg window is a recent(ish) change.
Cheers,
Mike

However, now I get a different error:

Can you send your script that triggers this bug? I wasn't the author of
this code, so I don't know how to get that path to execute -- but I'm
happy to work through your example until it's working.
(I suspect the intention here was m, n = x.shape[:2], but I can't test
it.)

Hmm, that's a bit hard, it's not really what one would call a
self-contained example...
the bug triggers when I load a rgb numpy float array with imshow (only
with floats, not with ints).
After some thought and trial, it's simple: these lines already trigger
the error:

Thanks, that helps a lot.
It seems to be working now -- I've committed this in r4643.

Hi all,
I found something strange in scipy.stats.percentileofscore
In [1]: from scipy import *
In [2]: a = rand(1)
In [3]: stats.percentileofscore(a,.2)
Out[3]: 20.0157565073
This OK.
In [4]: stats.percentileofscore(a,.0002)
Out[4]: 102.898311442

Hi,
I have (x,y) data that I want to fit to the formula

If you just want quick power law fit without turning to the other
solutions, you can just transform your

Mike,
Thanks for fixing those two errors that I introduced in 4374. I'm sorry
that I evidently did not test that code path, or even inspect it carefully.

Hi,
I just happened to do the same thing two days ago. If you want
uncertainties as well, here is some code that uses scipy.optimize. I
just put up a preliminary example on the scipy wiki:

I'm looking for something analogous to Matlab's ginput() and roipoly().
ginput() basically displays a crosshair on the current figure and allows
us to select points by clicking on it. It returns the x,y coordinates of
the points.
roipoly() allows us to define a polygon by clicking on the
