在 Dash 中获取条形图而不是散点图

Question

使用此代码

app.layout = html.Div([dcc.Graph(id='electricity',
                                figure= {'data':[
                                    go.Scatter(
                                    x=df['dayofweek'],
                                    y=df['Consumption [Wh]'],
                                    mode='markers')], 
                                'layout':go.Layout(title='Consumption per day',
                                                    xaxis = {'title':'dayofweek'},
                                                    yaxis = {'title':'Consumption'})})])

我使用 Dash 绘制了散点图。这没关系。但是我想知道如何在这里获得条形图而不是散点图？我尝试用 go.Bar 替换 go.Scatter 但得到了一个 ValueError:

ValueError: Invalid property specified for object of type plotly.graph_objs.Bar: 'mode'

Answer 1

错误说明问题所在

ValueError: Invalid property specified for object of type plotly.graph_objs.Bar: 'mode'

go.Scatter 有一个 mode 属性，但是 go.Bar 没有。因此，如果您想要条形图，请删除属性。
