從滑塊演示削減一個完整的例子，因爲背景虛化0.11變化，使用功能從背景虛化0.12.4：

from numpy import linspace, pi, sin 

from bokeh.io import curdoc 
from bokeh.layouts import row, widgetbox 
from bokeh.models import ColumnDataSource, Slider 
from bokeh.plotting import figure 

# Set up data 
x = linspace(0, 4*pi, 200) 
y = sin(x) 
source = ColumnDataSource(data=dict(x=x, y=y)) 

# Set up plot 
plot = figure(x_range=(0, 4*pi), y_range=(-2.5, 2.5)) 
plot.line('x', 'y', source=source, line_width=3, line_alpha=0.6) 

# Set up widgets 
amplitude = Slider(title="amplitude", value=1.0, start=-5.0, end=5.0) 
freq = Slider(title="frequency", value=1.0, start=0.1, end=5.1) 

# Set up callbacks 
def update(attrname, old, new): 
    # Get the current slider values 
    a = amplitude.value 
    k = freq.value 

    # Update the data for the new curve 
    source.data = dict(x=x, y=a*sin(k*x)) 

amplitude.on_change('value', update) 
freq.on_change('value', update) 

# Set up layout and add to document 
inputs = widgetbox(amplitude, freq) 
curdoc().add_root(row(inputs, plot, width=1200))
