#coding=utf-8

import matplotlib as mpl

import matplotlib.pyplot as plt

import numpy as np

y=df.loc[0:100, 4].values

y=np.where(y=='Iris-setosa',1,-1)

X=df.iloc[0:100,[0,2]].values

plt.rcParams['font.sans-serif'] = ['SimHei']

plt.rcParams['font.serif'] = ['SimHei']

plt.scatter(X[:50,0],X[:50,1],color='red',marker='o',label='setosa')

plt.scatter(X[50:100,0],X[50:100,1],color='blue',marker='x',label='versicolor')

plt.xlabel('长度')

plt.ylabel('宽度')

plt.legend(loc='upper left')

plt.show()
