Hallo, ich hab dies, habe es in Spider 5 und Spider mit Python 3.6. Aber die Schieber funktionieren nicht. Was muss ich noch machen, um die Schieber bewegen zu können?

• # Importing Libraries using import function
  import numpy as np
  import matplotlib.pyplot as plt
  from matplotlib.widgets import Slider
  
  # Setting Plot and Axis variables as subplots()
  # function returns tuple(fig, ax)
  fig, ax = plt.subplots()
  
  # Adjust the bottom size according to the
  # requirement of the user
  plt.subplots_adjust(bottom = 0.25)
  
  # Set the x and y axis to some dummy data
  t = np.arange(0.0, 1.0, 0.001)
  # Initial values of amplitude anf frequency
  # are denoted by a0 and f0
  a0 = 6
  f0 = 3
  s = a0*np.sin(2*np.pi*f0*t)
  
  # plot the x and y using plot function
  Plot, = plt.plot(t, s, lw = 3, color = 'green')
  plt.axis([0, 1, -10, 10])
  
  # Choose the Slider color
  axcolor = "White"
  
  # Set the frequency and amplitude axis
  frequency_axis = plt.axes([0.25, 0.1, 0.65, 0.03],
  facecolor = axcolor)
  amplitude_axis = plt.axes([0.25, 0.15, 0.65, 0.03],
  facecolor = axcolor)
  
  # Set the slider for frequency and amplitude
  frequency_slider = Slider(frequency_axis, 'Freq',
  0.1, 30.0, valinit = f0)
  amplitude_slider = Slider(amplitude_axis, 'Amp',
  0.1, 10.0, valinit = a0)
  
  # update() function to change the graph when the
  # slider is in use
  def update(val):
  amp = amplitude_slider.val
  freq = frequency_slider.val
  Plot.set_ydata(amp*np.sin(2*np.pi*freq*t))
  
  # update function called using on_changed() function
  # for both frequency and amplitude
  frequency_slider.on_changed(update)
  amplitude_slider.on_changed(update)
  
  # Display the plot
  plt.show()

Bei mir funktioniert das so problemlos.
