Stacked Bar GraphΒΆ

This is an example of creating a stacked bar plot with error bars using bar. Note the parameters yerr used for error bars, and bottom to stack the women's bars on top of the men's bars.

import numpy as np
import matplotlib.pyplot as plt

N = 5
men_means = [20, 35, 30, 35, 27]
women_means = [25, 32, 34, 20, 25]
men_std = [2, 3, 4, 1, 2]
women_std = [3, 5, 2, 3, 3]
ind = np.arange(N)    # the x locations for the groups
width = 0.35       # the width of the bars: can also be len(x) sequence, men_means, width, yerr=men_std, label='Men'), women_means, width, yerr=women_std, bottom=men_means,

plt.title('Scores by group and gender')
plt.xticks(ind, ('G1', 'G2', 'G3', 'G4', 'G5'))
plt.yticks(np.arange(0, 81, 10))
