Proper display of histograms with fixed bar widths

Community matplotlib-users

Hi All,
      I'm looking for a solution to properly display histograms of data
that is neither logarithmic, nor linear. Due to the nature of my data, I
manually specify my bins (which are neither fixed width, nor
logarithmic) - what I'd like to have is for each of my bins to have
equal bar widths.

      Basically the old 'deprecated' fixed bar widths would be exactly
what I need. Is there any possibility to mimic the old behavior using
the new API? If not, it would be nice if someone re-introduced the old
fixed-width functionality or some other solution since I guess I'm not
the only one plotting statistical data with manually specified bins. In
my case relative bar widths are an eye-sore (especially since my bins
have large orders of magnitude differences, but exactly some of the
smaller ones are of interest).

      Cheers,
            Greg

Yes, and mpl works fine with manually specified bins.
On the other hand, I don't see why you want to change the widths of
the bar. As far as I can see, that is not the correct representation
of the data.

Anyhow, here is a little example that makes your bars in equal width.
I never used "fixed width" bar so I'm not sure if this is what you
want.

aa = np.random.rand(100)
bins = np.array([0., 0.2, 0.3, 0.8, 1.])
p = hist(aa, bins)

rects = p[2]
for r in rects:
    r.set_width(0.1)
