双y轴
示例：https://plot.ly/python/multiple-axes/
import plotly.plotly as py
import plotly.graph_objs as go
trace1 = go.Scatter(
x=[1, 2, 3],
y=[40, 50, 60],
name='yaxis data'
)
trace2 = go.Scatter(
x=[2, 3, 4],
y=[4, 5, 6],
name='yaxis2 data',
yaxis='y2'
)
data = [trace1, trace2]
layout = go.Layout(
title='Double Y Axis Example',
yaxis=dict(
title='yaxis title'
),
yaxis2=dict(
title='yaxis2 title',
titlefont=dict(
color='rgb(148, 103, 189)'
),
tickfont=dict(
color='rgb(148, 103, 189)'
),
overlaying='y',
side='right'
)
)
fig = go.Figure(data=data, layout=layout)
plot_url = py.plot(fig, filename='multiple-axes-double')
你甚至可以用yaxis2, yaxis3, yaxis4 画4个y轴

from plotly import tools

trace1 = go.Scatter(x=[1, 2], y=[1, 2], name='(1,1)')

trace3 = go.Scatter(x=[1, 2], y=[1, 2], name='(2,1)')
trace4 = go.Scatter(x=[1, 2], y=[1, 2], name='(3,1)')
trace5 = go.Scatter(x=[1, 2], y=[1, 2], name='(5,1)')
trace6 = go.Scatter(x=[1, 2], y=[1, 2], name='(5,2)')
# specs 控制每个图表的大小
fig = tools.make_subplots(rows=5, cols=2,
specs=[[{}, {'rowspan': 2}],
[{}, None],
[{'rowspan': 2, 'colspan': 2}, None],
[None, None],
[{}, {}]],
print_grid=True)
fig.append_trace(trace1, 1, 1)
fig.append_trace(trace2, 1, 2)
fig.append_trace(trace3, 2, 1)
fig.append_trace(trace4, 3, 1)
fig.append_trace(trace5, 5, 1)
fig.append_trace(trace6, 5, 2)
fig['layout'].update(height=600, width=600, title='specs examples')
py.iplot(fig, filename='multiple-custom-sized-subplots')
