Dash Interactive Graph不能从Pandas Dataframe更新

pip install dash pandas

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

app = dash.Dash(__name__)

df = pd.read_csv('data.csv')  # 替换为你的数据文件路径

graph = dcc.Graph(
    id='interactive-graph',
    figure={
        'data': [
            {'x': df['x'], 'y': df['y'], 'type': 'scatter', 'mode': 'lines+markers'}
        ],
        'layout': {
            'title': 'Interactive Graph',
            'xaxis': {'title': 'X'},
            'yaxis': {'title': 'Y'}
        }
    }
)

app.layout = html.Div(children=[
    html.H1(children='Dash Interactive Graph'),
    graph
])

if __name__ == '__main__':
    app.run_server(debug=True)
