最近使用python里的matplotlib库绘图,想在代码结束时显示图片看看,结果图片一闪而过,附上我原来代码:
1
2
3
4
5
6
7
8
|
import matplotlib.pyplot as plt import numpy as np import pandas as pd ... ... #type(forecast)=< class 'pandas.core.frame.DataFrame'> pic01=m.plot(forecast) pic01.show() |
我上网查了一下,在遇到show()方法无法显示图片或者图片一闪而过,解决方案分两步:
1.加头文件,完整头文件如下:
1
2
3
4
5
|
import pandas as pd import matplotlib as mpl import matplotlib.pyplot as plt import numpy as np from numpy import * |
2.调用matplotlib.pyplot.show()方法:
完整代码为:
1
2
3
4
5
6
7
8
9
10
11
|
import pandas as pd import matplotlib as mpl import matplotlib.pyplot as plt import numpy as np from numpy import * ... ... #type(forecast)=< class 'pandas.core.frame.DataFrame'> pic01=m.plot(forecast) plt.show() #是plt.show()而不是pic01.show() pic01.savefig('temp.png') #存储图片,可选 |
以上这篇解决matplotlib库show()方法不显示图片的问题就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持服务器之家。
