Python 散点图未以虚线绘制方式渲染

我正在绘制一个仪表板，在一个散点图中有多个x特征，每个特征要么显示为直线，要么显示为带标记的直线

我已经根据我指定的要求构建了散点图，但是，当我在本地运行仪表板时，实际上看不到散点图

这是我写的代码

import dash
import dash_table
import plotly.graph_objs as go
import dash_html_components as html
import dash_core_components as dcc
from dash.dependencies import Input,Output
import pandas as pd
import os
import numpy as np
app = dash.Dash()
app.layout = html.Div(children=[
    dcc.Graph(
        id='supervisor'
    )
    ])
@app.callback(dash.dependencies.Output('supervisor','figure'))
def scattertable():
    trace0 = go.Scatter(
        x=supervisor['Características (D)'],
        y=supervisor['Mean Team Performance'],
        mode='lines',
        name='Caracteristicas (D)'
    )
    trace1 = go.Scatter(
        x=supervisor['Características (I)'],
        y=supervisor['Mean Team Performance'],
        mode='lines+markers',
        name='Características (I)'
    )
    trace2 = go.Scatter(
        x=supervisor['Características (S)'],
        y=supervisor['Mean Team Performance'],
        mode='lines',
        name='Características (S)'
    )
    trace3 = go.Scatter(
        x=supervisor['Características (C)'],
        y=supervisor['Mean Team Performance'],
        mode='lines+markers',
        name='Características (C)'
    )
    data = [trace0,trace1,trace2,trace3]
    return {"data": data,
            "layout": go.Layout(title="Relationship",
                                yaxis={"title":'Mean', "range":[0, max(supervisor['Mean Team Performance'])+1]},
                                xaxis={"title":'Characteristics', "tickangle":45}, )}

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

这是我的数据样本

}Dash需要输入才能成功进行回调。如果只想生成Plotly散点图，则不需要回调，只需将代码放入应用程序布局即可。我还将您的字典转换为熊猫数据框，用于创建情节

更新代码如下：

import dash
import dash_table
import plotly.graph_objs as go
import dash_html_components as html
import dash_core_components as dcc
from dash.dependencies import Input,Output
import pandas as pd
import os
import numpy as np

supervisor_df = pd.DataFrame.from_dict(supervisor)
fig = go.Figure()
category_dict = {'Características (D)':'lines',
                 'Características (I)':'lines+markers',
                 'Características (S)':'lines',
                 'Características (C)':'lines+markers'}
for category in category_dict.keys():
    fig.add_trace(go.Scatter(
        x=supervisor_df[category],
        y=supervisor_df['Mean Team Performance'],
        mode=category_dict[category],
        name=category
    ))
fig.update_layout(title="Relationship",
            yaxis={"title":'Mean', "range":[0, max(supervisor_df['Mean Team Performance'])+1]},
            xaxis={"title":'Characteristics', "tickangle":45}, )
app = dash.Dash()
app.layout = html.Div(children=[
    dcc.Graph(
        id='supervisor',
        figure=fig.to_dict()
    )
])
