如何使用plt.subplot增加绘图的大小

import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.add_subplot(111)

ax.set_aspect("equal")  # 设置子图的宽高比例相等
ax.set_xlim([x_min, x_max])  # 设置子图的X轴范围
ax.set_ylim([y_min, y_max])  # 设置子图的Y轴范围

ax.plot(x, y)  # 绘制曲线图
ax.scatter(x, y)  # 绘制散点图

import matplotlib.pyplot as plt

x = [1, 2, 3, 4, 5]
y = [2, 4, 6, 8, 10]

fig = plt.figure()
ax = fig.add_subplot(111)
ax.set_aspect("equal")
ax.set_xlim([0, 6])
ax.set_ylim([0, 12])
ax.plot(x, y)

plt.show()
