matplotlib中scatter报错module 'matplotlib' has no attribute 'scatter'

错误：

D:\pyPro\graph_recognation\venv\Scripts\python.exe D:/pyPro/graph_recognation/studyNew/huigui/simple_liner_regression.py
Traceback (most recent call last):
  File "D:/pyPro/graph_recognation/studyNew/huigui/simple_liner_regression.py", line 9, in <module>
    plt.scatter(x_data,y_data)
AttributeError: module 'matplotlib' has no attribute 'scatter'

原因：

导入包时用的是 

import matplotlib as plt

改为

import matplotlib.pyplot as plt
