解决matplotlib子图重叠问题

代码修改前：

import matplotlib.pyplot as plt
import seaborn as sns

def on_resize(event):
    print('当前画布大小为：{}x{}'.format(event.width, event.height))

if __name__ == '__main__':
    x = list(range(1, 6))
    y1 = [i ** 2 for i in x]
    y2 = [i ** 3 for i in x]

    fig = plt.figure()
    fig.canvas.mpl_connect('resize_event', on_resize)
    plt.title('Title')
    plt.axis('off')
    for i in range(321, 327):
        ax = fig.add_subplot(i)
        sns.kdeplot(y1, color='red', fill=True)
        sns.kdeplot(y2, color='blue', fill=True)
        ax.set_title('Subtitle')
        ax.set_xlabel('X Label')
        ax.set_ylabel('Y Label')
        ax.legend(['y1', 'y2'])

    plt.show()
