x, y: float or array type, shape (n, ), place the data to be displayed;
s: float or array type, shape (n, ), optional, the default value is rcParams['lines.markersize'] * * 2. This parameter is the size of the point, which can be an integer or a floating point number;

2. Sample

import matplotlib.pyplot as plt

x = result.PREDICT
y = result.WIN_OR_NOT
fig=plt.figure(figsize = (10,6))

plt.scatter(x, y, 
           s=10,
           color='b',
           label="girls")

plt.xlabel('PREDICT')
plt.ylabel('WIN_OR_NOT')
plt.title('scatter plot')
#添加图例
plt.legend()
plt.show()
