Dash Plotly -如何创建两个条件来绘制直方图？

import dash
import dash_core_components as dcc
import dash_html_components as html
import plotly.graph_objects as go

app = dash.Dash(__name__)

# 准备数据
x = [1, 2, 3, 4, 5]
y1 = [10, 8, 6, 4, 2]
y2 = [2, 4, 6, 8, 10]

# 创建图表
fig = go.Figure()
fig.add_trace(go.Bar(x=x, y=y1, name='条件1'))
fig.add_trace(go.Bar(x=x, y=y2, name='条件2'))

# 设置布局
layout = go.Layout(
    title='直方图',
    xaxis=dict(title='X轴'),
    yaxis=dict(title='Y轴'),
)

# 创建Dash应用程序的布局
app.layout = html.Div(children=[
    html.H1(children='Dash Plotly - 创建直方图'),
    dcc.Graph(
        id='histogram',
        figure=fig,
        layout=layout
    )
])

    app.run_server(debug=True)
