您需要將標簽名稱傳遞給xlabel和ylabel。如果它拋出錯誤 -TypeError: 'str' object is not callable然后重新啟動 ipython 內(nèi)核
import matplotlib.pyplot as plt
import pandas as pd
import pylab as pl
import numpy as np
%matplotlib inline
df = pd.read_csv("FuelConsumption.csv")
df.head()
df1 = df[['ENGINESIZE','CYLINDERS','FUELCONSUMPTION_COMB','CO2EMISSIONS']]
df1.head(9)
plt.scatter(df1.ENGINESIZE , df1.CO2EMISSIONS , color = "black")
plt.xlabel("enginesize")
plt.ylabel("emission")
plt.show()
