plotly python map subplot

Question

我有以下工作代码，

import pandas as pd
import io
import plotly.graph_objs as go 
from plotly.offline import plot

gb_state = pd.read_csv(io.StringIO(txt), delim_whitespace=True)

        subunitcolor = "rgb(255, 255, 255)",
    )

choromap = go.Figure(data=[data1,data2], layout=layout)
plot(choromap)

我正在尝试使用plotly生成地图的子图。为此，我添加了两个跟踪和两个域。

domain1 = dict( x = [0.0, 0.5], y = [0.0, 1.0] ), domain2 = dict( x = [0.5, 1.0], y = [0.0, 1.0] ),

我正在尝试连续打印两个地理图表。意思是1行和2列。当我执行上面的代码时，我只得到一个图。

任何人都可以发牢骚 - 代码出了什么问题？如何使用plotly绘制多个地图？
