轴未在 Matplotlib 中显示答案

【问题标题】：Axis not displaying in Matplotlib轴未在 Matplotlib 中显示
【发布时间】：2020-11-08 13:31:33
【问题描述】：

import matplotlib.pyplot as plt
import pandas as pd
import pylab as pl
import numpy as np
%matplotlib inline

!wget -O FuelConsumption.csv https://s3-api.us-geo.objectstorage.softlayer.net/cf-courses- 
data/CognitiveClass/ML0101ENv3/labs/FuelConsumptionCo2.csv

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()

当我尝试运行此代码时，我得到没有轴标签的散点图。如果有人可以帮助我，我如何获得轴标签？

【问题讨论】：

标签： python pandas dataframe matplotlib google-colaboratory

【解决方案1】：

您需要将标签名称传递给xlabel 和ylabel。如果它抛出错误 - TypeError: 'str' object is not callable 然后重新启动 ipython 内核

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()
