[Matplotlib-users] problem with histogram
Hello list,
I am trying to run the "histogram_demo_extended.py" on my mac 10.5.
I installed matplotlib through the scisoft package.
The normal hist command works fine but when I tried to use "align" or
"histtype" keyward I get this kind of error:
[Macintosh-2:~/optional/examples/pylab_examples] nino%
./histogram_demo_extended.py
Traceback (most recent call last):
File "./histogram_demo_extended.py", line 15, in
n, bins, patches = P.hist(x, 50, normed=1, histtype='stepfilled')
File
"/scisoft/i386/library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/matplotlib/pyplot.py",
line 1633, in hist
ret = gca().hist(*args, **kwargs)
File
"/scisoft/i386/library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/matplotlib/axes.py",
line 5064, in hist
p.update(kwargs)
File
"/scisoft/i386/library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/matplotlib/artist.py",
line 394, in update
raise AttributeError('Unknown property %s'%k)
AttributeError: Unknown property histtype
Can someone give me any advice?
Thanks a lot in advance.
nino

[Matplotlib-users] plotting numbers on axes in scientific notation
Hi, How can I plot numbers on the x and y axes in scientific notation? I have very large values on the y axis which I'd like to show as 1e9 and not 1 followed by 9 zeros. - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/___ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users
Re: [Matplotlib-users] interger to binary
Hi, Thanks a lot to all of you for your help. This looks very promising. I will test it on Monday. Regards, Marjolaine. >>> Michael Droettboom <[EMAIL PROTECTED]> 09/05/08 7:54 PM >>> You could do something like: def bitget(value, bit_number): return (value & (1 << bit_number)) != 0 which will return True or False for the given bit number, and this function works on numpy arrays. (Bits are numbered base-0 -- I don't know if that matches matlab).

It means the area of the circle circumscribing the marker, with that area measured in units of points squared. The strange choice of s as a measure of area instead of radius or diameter is for compatibility with Matlab.
