1、保存单张图片
import matplotlib.pyplot as plt
x=[0,1,2,3,4,5]
y=[0,2,4,6,8,10]
plt.plot(x,y)
plt.savefig( './result/exam_01.png')
plt.show()
2、创建文件夹并保存单张图片
import matplotlib.pyplot as plt
import os
x=[0,1,2,3,4,5]
y=[0,2,4,6,8,10]
plt.plot(x,y)
figure_save_path = "picture_folder"
if not os.path.exists(figure_save_path):
os.makedirs(figure_save_path)
plt.savefig(os.path.join(figure_save_path , 'exam_02.png'))
plt.show()
3、创建文件夹并保存多张图片
import matplotlib.pyplot as plt
import os
for i in range(0,3,1):
x=[i,1,2,3,4,5]
y=[0,2,4,6,8,10]
name_list=["one","two","three"]
plt.plot(x,y)
figure_save_path = "picture_folder_many"
if not os.path.exists(figure_save_path):
os.makedirs(figure_save_path)
plt.savefig(os.path.join(figure_save_path , name_list[i]))
plt.show()
