ipywidgets StaticInteract绘制所有图像组合

Question

我用iPython笔记本来测试交互功能。下面的例子（来自here）几个月前对我来说效果不错。但是，如果我现在运行它，它会从可能的组合中打印出所有的图像。我不确定这是否重复，但this没有帮助。在

%matplotlib inline

import numpy as np
import matplotlib.pyplot as plt
import matplotlib as mpl

# mpl.rcParams['figure.max_open_warning'] = 1

def plot(amplitude, color):

    fig, ax = plt.subplots(figsize=(4, 3),
                           subplot_kw={'axisbg':'#EEEEEE',
                                       'axisbelow':True})

    ax.grid(color='w', linewidth=2, linestyle='solid')
    x = np.linspace(0, 10, 1000)
    ax.plot(x, amplitude * np.sin(x), color=color,
            lw=5, alpha=0.4)
    ax.set_xlim(0, 10)
    ax.set_ylim(-1.1, 1.1)

    return fig

from ipywidgets import StaticInteract, RangeWidget, RadioWidget

StaticInteract(plot,
               amplitude=RangeWidget(0.1, 1.0, 0.1),
               color=RadioWidget(['blue', 'green', 'red']))

这是输出： 你能帮助我吗？在

这就是你如何接近它。在

%matplotlib inline
import numpy as np
import matplotlib.pyplot as plt
import matplotlib as mpl
from ipywidgets import interact, FloatSlider, RadioButtons

amplitude_slider = FloatSlider(min=0.1, max=1.0, step=0.1, value=0.2)
color_buttons = RadioButtons(options=['blue', 'green', 'red'])
# decorate the plot function with an environment from the UIs:
@interact(amplitude=amplitude_slider, color=color_buttons)
def plot(amplitude, color):
    fig, ax = plt.subplots(figsize=(4, 3),
                       subplot_kw={'axisbg':'#EEEEEE',
                                   'axisbelow':True})

    ax.grid(color='w', linewidth=2, linestyle='solid')
    x = np.linspace(0, 10, 1000)
    ax.plot(x, amplitude * np.sin(x), color=color,
        lw=5, alpha=0.4)
    ax.set_xlim(0, 10)
    ax.set_ylim(-1.1, 1.1)
