labels = [‘G1’, ‘G2’, ‘G3’, ‘G4’, ‘G5′]

men_means = [20, 35, 30, 35, 27]

women_means = [25, 32, 34, 20, 25]

width = 0.35  # the width of the bars: can also be len(x) sequence

fig, ax = plt.subplots(figsize=(5, 3), dpi=200)

ax.bar(labels, men_means, width, label=’Men’, color=’green’)

ax.bar(labels, women_means, width, bottom=men_means, label=’Women’, color=’red’)

ax.set_ylabel(‘Scores’)

ax.set_title(‘Scores by group and gender’)

ax.legend()

for a, b in zip(np.arange(len(labels)), men_means):

plt.text(a, b / 2, ‘%.0f’ % b, ha=’center’, va=’bottom’, fontsize=7)

 

for a, b, c in zip(np.arange(len(labels)), men_means, women_means):

plt.text(a, b + c / 2, ‘%.0f’ % c, ha=’center’, va=’bottom’, fontsize=7)

 

plt.show()

效果如下：
