以绘图方式填充python中两点之间的区域

import matplotlib.pyplot as plt
import numpy as np

x = [1, 3]
y = [2, 4]

fill_x = np.linspace(x[0], x[1], 100)

fill_y = np.linspace(y[0], y[1], 100)

plt.plot(x, y, 'ro-')  # 绘制两点之间的连线
plt.fill_between(fill_x, fill_y, y[0], color='blue', alpha=0.3)  # 填充两点之间的区域

plt.title('Fill Area Between Two Points')
plt.xlabel('X')
plt.ylabel('Y')

plt.show()
