滑块中带有时间戳的Dash绘图问题

import dash
import dash_core_components as dcc
import dash_html_components as html
from dash.dependencies import Input, Output

app = dash.Dash(__name__)

app.layout = html.Div([
    dcc.Slider(
        id='timestamp-slider',
        min=0,
        max=100,
        value=0,
        step=1
    ),
    dcc.Graph(id='plot')
])

@app.callback(
    Output('plot', 'figure'),
    [Input('timestamp-slider', 'value')]
)
def update_plot(timestamp):
    # 根据时间戳获取对应的数据
    data = get_data(timestamp)
    
    # 创建绘图对象并设置数据
    fig = create_figure(data)
    
    return fig
