[Matplotlib-users] Error due to unusual font file
Trying to get a colleague to start using python, he ran into trouble,
getting an error exit whenever he tried to fire up
ipython -pylab
After much searching, he figured it out... it appears that a small patch may be
in order. Here is his note :
I found it: I have a font installed in my personal fonts
directory that has non-integral sides for the bounding box
of the font.
Fortunately, it seems like once I move my ~/.fonts
directory off to the side and then run
ipython -pylab
then some of that configuration info must be cached, since I
am able to move my .fonts file back and still have my ipython
-pylab come up.
The offending line is in the return statement below
#Convert string the a python type
_to_int = int
_to_float = float
_to_str = str
def _to_list_of_ints(s):
s = s.replace(',', ' ')
return [_to_int(val) for val in s.split()]
and I think a fix would be along the lines of Alan's remark:
return [_to_int(_to_float(val)) for val in s.split()]
This is in the file
/glb/apps/sss/epd/2.5.4.2.30201/lib/python2.5/site-packages/ma
tplotlib-0.98.5.2n1-py2.5-linux-x86_64.egg/matplotlib/afm.py
Anyway, it works for me.

[Matplotlib-users] controlling tick label size
Trying to find a simple way to shrink the tick labels for this plot -
since I can have many tiny histograms, the labels need to be smaller,
but it isn't obvious to me how to simply shrink them.
code snippet...
num = len(datasets)
fig = plt.figure()
rows = np.int(np.sqrt(num))
cols = np.int(float(num)/float(rows)+.9)
for i in range(num):

ax.hist(datasets[i][np.isfinite(datasets[i])], bins=60 )
ax.set_xlabel(labels[i], size = 9)

[Matplotlib-users] open multiple plots from a program
I have been trying to figure out how to open up multiple plots from a traits program, without much luck. I tried threads, no joy. Is there a simple way to get multiple plots to come up? Would it work to fork off new processes for each plot? I haven't done that in python before, just perl, so before I dig too deeply into it, I thought I'd ask around. -- --- | Alan K.

Re: [Matplotlib-users] Filling between curves conditionally

Incidentally, when you do it with ax.plot() instead you can see more
easily that the corners where the two sinusoidal functions intersect
are getting kind of chopped off by the polygon filling. Don't know if
there's an easy way to fix that - maybe by forcing the list of polygon
vertices to always explicitly include the points of intersection
between the functions being filled_between? Or maybe just by
increasing the number of vertices, though I assume that would slow
things down.
Some time back, I wrote code to generate a fairly complex polyfill in
a plot in R,
http://www.oplnk.net/~ajackson/weather/Temperature_2000.png
The key bit of code to find the intersections between all the curves
to fill the corners correctly is here (note that this is R code):

(0.0 t) (t 1.0) ) {

}
else if ( (0.0 s) || (s 1.0) ||
(0.0 t) || (t 1.0) ) {

}

Re: [Matplotlib-users] Non-linear Regression to a Histogram
I have an example of fitting distributions to bus arrival times using 'R' that may be helpful. I wanted to calculate the latest time I could arrive at the bus stop and have a better than 95% chance of catching the bus.
