我正在嘗試使用循環打印圖表。數據在一個列表中。這是我的代碼當前的外觀（我在 for 循環中收到語法錯誤）：import dashimport dash_core_components as dccimport dash_html_components as htmlimport pandas as pdimport plotly.graph_objs as godfs = [pd.DataFrame({"xaxis":["thing","otherthing","anotherthing"],"yaxis":[64,14,62]}),pd.DataFrame({"xaxis":["newthing","newotherthing","newanotherthing"],"yaxis":[344,554,112]})]external_stylesheets = ['https://codepen.io/chriddyp/pen/bWLwgP.css']app = dash.Dash(__name__, external_stylesheets=external_stylesheets)g = 0app.layout = html.Div(children=[ for df in dfs: dcc.Graph(id='example-graph'+str(g),figure={'data': [go.Bar(x=df['xaxis'],y=df[("yaxis")],name="yaxis")]}) ] g = g + 1)if __name__ == '__main__': app.run_server(debug=True)我希望它看起來像這樣： 我該怎么做呢？

該children屬性基本上是一個列表，您可以先在通用循環中生成列表，然后將其添加到 Div 中。
這是工作片段，
import dash
import dash_core_components as dcc
import dash_html_components as html
import pandas as pd
import plotly.graph_objs as go
df1 = pd.DataFrame({"xaxis":["thing","otherthing","anotherthing"],"yaxis":[64,14,62]})
df2 = pd.DataFrame({"xaxis":["newthing","newotherthing","newanotherthing"],"yaxis":[344,554,112]})
external_stylesheets = ['https://codepen.io/chriddyp/pen/bWLwgP.css']
app = dash.Dash(__name__, external_stylesheets=external_stylesheets)
output = []
#here you can define your logic on how many times you want to loop
for i in range(0,2):
output.append(dcc.Graph(id='example-graph'+str(i),figure={'data': [go.Bar(x=df1['xaxis'],y=df1[("yaxis")],name="yaxis")]}))
app.layout = html.Div(children=output)
if __name__ == '__main__':
app.run_server(debug=True)
