Django + plotly-dash:无法并排呈现图形

Question

我遵循了这个Subplot ( Side to side ) in python Dash和How to add multiple graphs to Dash app on a single browser page?，找到了一种在我的模板中实现图形并排渲染的方法。

我不能让它工作，图形的大小调整得很好，但它们一直在渲染一个在另一个的下方。我对哪里出了问题感到困惑，而且由于我只是拿起dash，我正在努力找出问题的根本原因。

更新:正如我在评论中提到的，我已经尝试将graph1和graph2作为一个div标签和显示的子级包含在内，但是它仍然不能让两个图形彼此相邻。

下面是我的文件的样子：

import dash_core_components as dcc
import dash_html_components as html
from dash.dependencies import Input, Output
import plotly.graph_objs as go
from django_plotly_dash import DjangoDash
import pandas as pd
import dash

external_stylesheets =  'home/ubuntu/exostocksaas/staticfiles/css/style.css'
app = DjangoDash('tryout', external_stylesheets=external_stylesheets)

# assume you have a "long-form" data frame
# see https://plotly.com/python/px-arguments/ for more options
df_bar = pd.DataFrame({
    "Fruit": ["Apples", "Oranges", "Bananas", "Apples", "Oranges", "Bananas"],
    "Amount": [4, 1, 2, 2, 4, 5],
    "City": ["SF", "SF", "SF", "Montreal", "Montreal", "Montreal"]
})

fig = px.bar(df_bar, x="Fruit", y="Amount", color="City", barmode="group")

app.layout = html.Div(children=[
    
    
    # All elements from the top of the page
html.Div(children=[
        
        
        html.Div(children=[
            html.H1('Hello Dash'),

            html.Div(''' Dash: A web application framework for Python.'''),

                dcc.Graph(id='graph1',figure=fig, style={"width":500, "margin": 10,'display': 'flex'}),  
            
                html.H3('Hello Dash'),
                dcc.Graph(id='graph2',figure=fig, style={"width":500, "margin": 10,'display': 'flex'}),   
], 
),
        html.Div(children=[
             html.H1('Hello Dash', style={"width":500, "margin": 0,'display': 'flex'}),

             html.Div('''Dash: A web application framework for Python.''', style={"width":500, "margin": 0,'display': 'inline-block'}),
                dcc.Graph(id='graph2',figure=fig, style={"width":500, "margin": 0,'display': 'flex'}),                  
                ]),
    
        html.H1('Hello Dash'),

        html.Div('''Dash: A web application framework for Python.'''),
        dcc.Graph(id='graph3',figure=fig, style={"width":500, "margin": 0,'display': 'flex'}
        ),  

    ], className='row'),

    html.Div([
        html.H1(children='Hello Dash'),

        html.Div(children='''
            Dash: A web application framework for Python.
        '''),
        
dash_table.DataTable(
    id='table',

    columns=[{"name": i, "id": i} for i in df_bar.columns],
    data=df_bar.to_dict('records'),
    sort_action='native',
    filter_action='native',
    export_format='csv',


    style_cell={'textAlign': 'center', 'font-size' : '16px','width': '10px',
        'overflow': 'hidden'
},


    style_data_conditional=[
        {
            'if': {'row_index': 'odd'},
            'backgroundColor': 'rgb(248, 248, 248)'
        }
    ],
    style_header={
        'backgroundColor': 'rgb(230, 230, 230)',
        'fontWeight': 'bold',
        'font-size' : '20px'
    }

)
    ], className='six columns')
    
])

还是不走运，我找不到办法让它工作

我在本地运行了它，它起作用了。我去掉了样式表，这样我就可以使用style属性在这里显示CSS。

    html.Div(children=[

        html.Div(
            style=dict(display='flex', height=500),
            children=[
                html.H1('Hello Dash'),

                html.Div(''' Dash: A web application framework for Python.'''),

                dcc.Graph(id='graph1', figure=fig,
                          style={"width": 500, "margin": 10, 'display': 'flex'}),

                html.H3('Hello Dash'),
                dcc.Graph(id='graph2', figure=fig,
                          style={"width": 500, "margin": 10, 'display': 'flex'}),
            ],
        ),
    ], className='row'),
