Matplotlib之解决plt.savefig()保存多张图片有重叠的问题

import matplotlib.pyplot as plt
def ch_graph(num_clusters, ch_score, filepath, method, module):
    # Plot ch graph
    plt.plot(num_clusters, ch_score, 'bx-')
    plt.xlabel('Number of cluster')
    plt.ylabel('Calinski-Harabasz Score')
    plt.title('Calinski-Harabasz Score against Number of Cluster')
    plt.grid(True)
	filename = 'ch_graph_one.png'
    folder = 'Picture/'
    ch_filepath = filepath + '/' + folder + filename
    plt.savefig(ch_filepath)
def elbow_graph(num_clusters, Sum_of_squared_distances, filepath, method, module):
    # Plot ch graph
    plt.plot(num_clusters, Sum_of_squared_distances, 'bx-')
    plt.xlabel('Number of cluster')
    plt.ylabel('Sum of squared dist')
    plt.title('Sum of squared dist against Number of Cluster')
    plt.grid(True)
    filename = 'elbow_graph_one.png'
    folder = 'Picture/'
    elbow_filepath = filepath + '/' + folder + filename
    plt.savefig(elbow_filepath)

fig.canvas.draw_idle()   # need this if 'transparent=True' to reset colors

import matplotlib.pyplot as plt

#保存图片
#bbox_inches='tight'表示指定将图表多余的空白区域裁减掉
plt.savefig('test.png', bbox_inches='tight')
#显示图片
plt.show()

plt.savefig('test.svg', bbox_inches='tight')
#显示图片
plt.show()
