如何在python中正确使用for循环从csv绘制多行？

import csv
import matplotlib.pyplot as plt

# 读取CSV文件
with open('data.csv', 'r') as file:
    reader = csv.reader(file)
    next(reader)  # 跳过标题行
    data = list(reader)

# 提取需要绘制的数据
x = [row[0] for row in data]
y1 = [row[1] for row in data]
y2 = [row[2] for row in data]

# 绘制多行数据
plt.plot(x, y1, label='Line 1')
plt.plot(x, y2, label='Line 2')

# 添加图例、标题和坐标轴标签
plt.legend()
plt.title('Multiple Lines from CSV')
plt.xlabel('X-axis')
plt.ylabel('Y-axis')

# 显示图形
plt.show()
