Plot histogram with colors taken from colormap

Question

I want to plot a simple 1D histogram where the bars should follow the color-coding of a given colormap.

Here\'s an MWE:

import numpy as          


        

Answer 1

I like Bas Swinckels answer, but given that the colormap cm take as parameter a value between 0 and 1, a simpler algorithm would be like this

import matplotlib.pyplot as plt

Ntotal = 1000
data = 0.05 * n.random.randn(Ntotal) + 0.5

cm = plt.cm.RdBu_r

n, bins, patches = plt.hist(data, 25, normed=1, color='green')
for i, p in enumerate(patches):
    plt.setp(p, 'facecolor', cm(i/25)) # notice the i/25

plt.show()
