# encoding=utf-8
import pandas as pd
import matplotlib.pyplot as plt
import numpy as np
plt.rcParams['font.sans-serif']=['SimHei']#用来正常显示中文标签
plt.rcParams['font.serif'] = ['SimHei']
file = 'https://archive.ics.uci.edu/ml/machine-learning-databases/iris/iris.data'
df = pd.read_csv(file,header=None)

y=df.loc[0:100,4].values
y=np.where(y == 'Iris-setosa',-1,1)

x=df.iloc[0:100,[0,2]].values
plt.scatter(x[:50,0], x[:50,1], color='red', marker='o',lable='setosa')
plt.scatter(x[50:100,0], x[50:100,1], color='blue', marker='x',lable='versicolor')

plt.xlabel('花瓣长度')
plt.ylabel('花茎长度')
plt.legend(loc = 'upper left')
plt.show()

AttributeError: Unknown property lable

Answer 1

你的lable写错了，应该是label才对。记得采纳哦

Answer 2

直接删除参数label =          

Answer 3

plt.scatter(x[:50,0], x[:50,1], color='red', marker='o',lable='setosa')plt.scatter(x[50:100,0], x[50:100,1], color='blue', marker='x',lable='versicolor')这两个里面的参数改一下就可以plt.scatter(x[:50,0],x[:50,1],color='red',marker='o')plt.scatter(x[50:100,0],x[50:100,1],color='blue',marker='x')
