Re: [Numpy-discussion] Producing a Histogram When Bins Are Known

I tried this and it put ranges on y from 0 to 0.45 and x from 5 to 50. import numpy as np import pylab v = np.array([20, 15,10,30, 50, 30, 20, 25, 10]) #Plot a normalized histogram print np.linspace(0,50,10) pylab.hist(v, normed=1, bins=np.linspace(0,9,10), range=(0,100)) pylab.show() I added t

Did you try using the parameter range? I do something like this. regards ax = fig.add_subplot(1,1,1) > pylab.title(r'\Large BCG NO radio distribution $ \rm{TITLE}$') > n, bins, patches = pylab.hist(values, bins=math.sqrt(len(values)), > range=(numpy.mean(values)-3*scientificstat.standardDeviation

It's good to have some extra references for NumPy. Actually, it looks like exercising histogram in NunPy has gotten me past the difficulties with hist in matplotlib. I Is there a matplotlib or Pylab mailing list. It uses hist and looks very much like histogram, but has some parameters that I ne

Thanks. That sounds like it should help a lot. Finding meaningful examples anywhere hasn't been easy. I thought I'd look through Amazon for books on Python and scientific uses. I found almost all were written by authors outside the US, and none seemed to talk about items like matplotlib. Ezdraw
