如何在bokeh中根据用户选择的单选按钮更改图表类型

from bokeh.models import RadioButtonGroup
from bokeh.plotting import figure, show
from bokeh.layouts import column
from bokeh.io import curdoc

options = ["折线图", "柱状图", "散点图"]
labels = ["Line", "Bar", "Scatter"]
radio_button_group = RadioButtonGroup(labels=labels, active=0)

p = figure()

def update_plot(attr, old, new):
    if new == 0:
        p.line([1, 2, 3], [4, 5, 6], line_color="blue")
    elif new == 1:
        p.vbar(x=[1, 2, 3], width=0.5, bottom=0, top=[4, 5, 6], color="red")
    elif new == 2:
        p.circle([1, 2, 3], [4, 5, 6], size=10, fill_color="green")

radio_button_group.on_change('active', update_plot)

layout = column(radio_button_group, p)
curdoc().add_root(layout)
show(layout)
