    在matplotlib的官网上有很多例子,可以学习参考。https://matplotlib.org/stable/gallery/index.html

    import matplotlib.pyplot as plt
    import numpy as np
    
    
    labels = ['G1', 'G2', 'G3', 'G4', 'G5']
    men_means = [20, 34, 30, 35, 27]
    women_means = [25, 32, 34, 20, 25]
    
    x = np.arange(len(labels))  # the label locations
    width = 0.35  # the width of the bars
    
    fig, ax = plt.subplots()
    rects1 = ax.bar(x - width/2, men_means, width, label='Men')
    rects2 = ax.bar(x + width/2, women_means, width, label='Women')
    
    # Add some text for labels, title and custom x-axis tick labels, etc.
    ax.set_ylabel('Scores')
    ax.set_title('Scores by group and gender')
    ax.set_xticks(x)
    ax.set_xticklabels(labels)
    ax.legend()
    
    ax.bar_label(rects1, padding=3)
    ax.bar_label(rects2, padding=3)
    
    fig.tight_layout()
    
    plt.show()
