如何多次更新波克图中的绘图特征(悬停工具细节和x_range)？

import bokeh.plotting as plt
from bokeh.models import HoverTool
from bokeh.layouts import column
from bokeh.io import curdoc

# 定义绘图函数
def draw_plot(x_range, hover_tool_details):
    # 创建波克图
    p = plt.figure(x_range=x_range)

    # 设置悬停工具细节
    hover = HoverTool(tooltips=hover_tool_details)
    p.add_tools(hover)

    # 绘制波克图
    # ...

    return p

# 初始的波克图参数
initial_x_range = [0, 10]
initial_hover_tool_details = [("x", "@x"), ("y", "@y")]

# 创建初始的波克图
plot = draw_plot(initial_x_range, initial_hover_tool_details)

# 更新波克图的回调函数
def update_plot():
    # 获取新的参数
    new_x_range = [0, 20]
    new_hover_tool_details = [("x", "@x"), ("y", "@y"), ("z", "@z")]

    # 更新波克图
    new_plot = draw_plot(new_x_range, new_hover_tool_details)

    # 替换原有的波克图
    layout.children[0] = new_plot

# 创建更新按钮
update_button = Button(label="Update Plot")
update_button.on_click(update_plot)

# 创建布局
layout = column(update_button, plot)

# 将布局添加到文档
curdoc().add_root(layout)
