Python display same bin width for different bin sizes

I have this code

bins = [0,1,10,20,30,40,50,75,100]
plt.figure(figsize=(15,15))
plt.hist(df.v1, bins = bins)

My problem is that the bin widths as they appear in the figure are proportional to their range in bins. However, I want all bins to come out having the same width.

I'm not sure how you'll make sense of the result, but you can use numpy.histogram to calculate the height of your bars, then plot those directly against an arbitrary x-scale.

x = np.random.normal(loc=50, scale=200, size=(2000,))
bins = [0,1,10,20,30,40,50,75,100]
fig = plt.figure()
ax = fig.add_subplot(211)
ax.hist(x, bins=bins, edgecolor='k')
ax = fig.add_subplot(212)
h,e = np.histogram(x, bins=bins)
ax.bar(range(len(bins)-1),h, width=1, edgecolor='k')
