# 1、准备数据
x = [225.98, 247.07, 253.14, 457.85, 241.58, 301.01, 20.67, 288.64,
163.56, 120.06, 207.83, 342.75, 147.9, 53.06, 224.72, 29.51,
21.61, 483.21, 245.25, 399.25, 343.35]
y = [196.63, 203.88, 210.75, 372.74, 202.41, 247.61, 24.9, 239.34,
140.32, 104.15, 176.84, 288.23, 128.79, 49.64, 191.74, 33.1,
30.74, 400.02, 205.35, 330.64, 283.45]
# 2、创建画布
plt.figure(figsize=(20, 8), dpi=80)
# 3、绘制图像
plt.scatter(x, y)
# 4、显示图像
plt.show()
