如何用熊猫做一个简单的情节

Question

我想用pandas做一个简单的情节，但是得到了这个错误：

import pandas as pd
import matplotlib.pyplot as plt
import pandas

df = pandas.read_csv("volvo_volvo.csv");
dfw = pandas.DataFrame(data = df, columns=['PriceDisplay','Year','Odometer'])
y = df.PriceDisplay.values
x = df.Odometer.values

df.plot(x=x, y=y, marker='.')
plt.show()

IndexError：指数超出范围

CSV文件列价格和里程表：
