python - matplotlib：再次单击按钮后删除滑块

Question

我希望通过单击按钮 WR3(='WR2.2') 使滑块 (f01) 消失。这样就没有覆盖并且滑块是新的。我不知道如何更新或删除这个完整的滑块。这是我的代码：

from numpy import pi, sin
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.widgets import Slider, Button, RadioButtons
from matplotlib.patches import Ellipse
from scipy.optimize import fsolve
import pylab
w0=1.7
lamb=0.4119
f0=lamb*1.0/(299.792458)
#lamb=f0*1.0/(299.792458)
d_in=80.0
R1=46.672
R2=686.468
foc=1/((1/R1)+(1/R2))
c=299792458000.0
zR=np.pi*w0**(2)/(c/(f0*1000000000.0))
fig = plt.figure(figsize=(20,10))
ax = fig.add_subplot(111)
x_start=0.0
x_end=500.0
ax.xaxis.set_ticks(np.arange(x_start,x_end+20.0, 20.0))
axis_color = 'lightgoldenrodyellow'
fig.subplots_adjust(left=0.25, bottom=0.35)
x = np.arange(x_start,x_end, 0.01)

w0_0 = 1.7
f0_0 = 727.82825
w1_0=w0*np.sqrt(1.0/(((d_in)/foc-1.0)**(2)+(zR/foc)**(2)))
d_in_0=80.0
d_out_0=foc+(d_in-foc)/(((d_in)/foc-1.0)**(2)+(zR/foc)**(2))

# function 1 and 2
def signal(w0,f0):
    return w0*np.sqrt(1.0+(x/(np.pi*w0**(2)/(c/(f0*1000000000.0))))**(2))
[line] = ax.plot(x, signal(w0_0, f0_0), linewidth=2, color='red')
WR3_button_ax = fig.add_axes([0.025, 0.7, 0.05, 0.05])
WR3_button = Button(WR3_button_ax, 'WR2.2:', color=axis_color, hovercolor='0.975')

# Define an axes area and draw a slider in it
w0_slider_ax  = fig.add_axes([0.25, 0.2, 0.65, 0.03], axisbg=axis_color)
w0_slider = Slider(w0_slider_ax, 'w0 [mm]', 0.1, 9.2, valinit=w0_0)

def WR3_button_on_clicked(mouse_event):
    f01_slider_ax = fig.add_axes([0.25, 0.25, 0.65, 0.03], axisbg=axis_color)
    f01_slider = Slider(f01_slider_ax, 'f0 [GHz]', 340.0, 500.0, valinit=d_in)
    w0_slider.set_val(1.5)
    f01_slider.set_val(340.0)
    def sliders_on_changed(val):
        line.set_ydata(signal(w0_slider.val, f01_slider.val))
        fig.canvas.draw_idle()
    f01_slider.on_changed(sliders_on_changed)

WR3_button.on_clicked(WR3_button_on_clicked)

plt.show()

我创建了这个函数，它是关于滑块 f01 的。谢谢
