Setting the bin content of a histogram

Community matplotlib-users

Hi all,

I'm currently using the hist plot from matlibplot. Here I have the following
question: is there an easy way to set the bin content of a specified bin?
For example, I would like to call set_bin_content(bin_index=1, value=10000)
once instead of filling in 10000 times the same value.

Thank you very much.
Best regards

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()
