[Python] Rescale axes concerning visible artists only

I have a request regarding the use of autoscale_view(). I was expecting it to scale the plot considering only the visible artists, but it does not have such an effect.

I have a small test script as follows, any help is welcome:

import matplotlib.pyplot as plt
import numpy as np

x1 = np.linspace(0, 10, 100)
y1 = np.sin(x1)
x2 = np.linspace(5, 15, 100)
y2 = np.cos(x2)

fig, ax = plt.subplots()
ax.set_title('Click on legend line to toggle line on/off')
(line1, ) = ax.plot(x1, y1, lw=2, label='1 Hz')
(line2, ) = ax.plot(x2, y2, lw=2, label='2 Hz')
leg = ax.legend()

lines = [line1, line2]
map_legend_to_ax = {} # Will map legend lines to original lines.

pickradius = 5
for legend_line, ax_line in zip(leg.get_lines(), lines):
legend_line.set_picker(pickradius)
map_legend_to_ax[legend_line] = ax_line

def on_pick(event):
legend_line = event.artist
ax_line = map_legend_to_ax[legend_line]
visible = not ax_line.get_visible()
ax_line.set_visible(visible)
legend_line.set_alpha(1.0 if visible else 0.2)

ax.relim()
ax.autoscale_view()
fig.canvas.draw()

fig.canvas.mpl_connect('pick_event', on_pick)
plt.show()
