安裝 pip ＆ matplotlib &numpy &dateutil

pip install matplotlib
pip install matplotlib
pip install numpy
pip install dateutil

可能用到msvcp.dl

將 msvcp.ddl 放到C:\windows\system32

檢查 :

import matplotlib.pyplot as plt1
print(dir(plt) == dir(plt1))

輸出:

True

------------------------------------------------------------------------------------------

測試

import matplotlib.pyplot as plt1
plt.plot([1,2,3])
plt.ylabel('some numbers')
plt.show()
