为每个matplotlib保存图形

Question

如何为for循环中生成的每个图保存一个图

这是我的密码：

for frame in all_frames:
  test[frame.columns[0]].plot(kind = 'line', x = 'date')
  plt.ylabel('Percent Change from Month and Year Prior')

Answer 1

只需在for循环中添加^{}：

for frame in all_frames:
    test[frame.columns[0]].plot(kind = 'line', x = 'date')
    plt.ylabel('Percent Change from Month and Year Prior')
    plt.savefig('{}'.format(frame.columns[0]))
