python - Wonder-twin power "Zoom to rectangle"激活？

Question

有没有办法在显示 matplotlib 图形时默认自动激活“缩放到矩形”工具？

import numpy as np
import matplotlib.pyplot as plt
x = np.arange(-300, 300)
y = x**2-7*x
fig = plt.figure()
ax = fig.add_subplot(1,1,1)
plt.plot(x, y)
# Add something here to activate the "Zoom to rectangle" tool?
plt.show()

Answer 1

这对我有用:

plt.get_current_fig_manager().toolbar.zoom()
