You can do this by separating the histogram calculation from the  
plotting.

import numpy as np
import matplotlib as mpl
import matplotlib.pyplot as plt

# generate data here; for example
data = np.random.randn(500)

myHist, myBinEdges = np.histogram(data)

# edit myHist to your heart's delight

wid = myBinEdges[1:] - myBinEdges[:-1]
plt.bar(myBinEdges[:-1], myHist, width=wid)
plt.show()
