添加组条形图作为绘图中的子图

我想创建分组（barmode='组'）plotly 中的条形图子图。现在的问题是，plotly 不会创建条形图作为痕迹。相反，分组条形图被创建为条形轨迹列表。因此，我不知道如何创建一个包含分组条形图作为子图的图形（即使用添加分组条形图图.append_trace()).

例如，如何使用在中创建的条形图创建子图这个样本 https://plot.ly/python/bar-charts/#grouped-bar-chart:

import plotly.plotly as py
import plotly.graph_objs as go
trace1 = go.Bar(
    x=['giraffes', 'orangutans', 'monkeys'],
    y=[20, 14, 23],
    name='SF Zoo'
)
trace2 = go.Bar(
    x=['giraffes', 'orangutans', 'monkeys'],
    y=[12, 18, 29],
    name='LA Zoo'
)
data = [trace1, trace2]
layout = go.Layout(
    barmode='group'
)
fig = go.Figure(data=data, layout=layout)
plot_url = py.plot(fig, filename='grouped-bar')

YES! New to plot.ly and had this issue, and as mentioned in my comment, I couldn't just do it in pandas/matplotlib for various reasons. But through the magic of subplots, you can in fact recreate multi-trace plots by just subploting them together.

import plotly.plotly as py
import plotly.graph_objs as go
from plotly import tools

trace1 = Bar(
    x=['giraffes', 'orangutans', 'monkeys'],
    y=[20, 14, 23],
    name='SF Zoo'
)
trace2 = Bar(
    x=['giraffes', 'orangutans', 'monkeys'],
    y=[12, 18, 29],
    name='LA Zoo'
)
trace3 = Scatter(
  x=['giraffes', 'orangutans', 'monkeys']
  ,y=[33,20,17]
  ,name='subplots ftw'
  )


fig = tools.make_subplots(rows=2, cols=1, shared_xaxes=True)

fig.append_trace(trace3, 1,1)
fig.append_trace(trace1, 2, 1)
fig.append_trace(trace2,2,1)


fig['layout'].update(height=600, width=600)
iplot(fig)
