Grouped box plot with multiple axes

📊 Plotly Python
1

Hello there!
I am trying to plot a grouped box plot with 2 y axes, one of the left and one on the right. I have found examples for box plots with multiple axes but I have no clues about how to do it with grouped box plots.
Do you know whether it is possible and how to do it, eventually?
Thanks in advance!

Hi @giograno,

Here’s an example to get you started. Here the “kale” and “radishes” traces use the yaxis on the left, while the “carrots” trace uses the yaxis on the right.

import plotly.graph_objs as go
import plotly.offline as offline
offline.init_notebook_mode(connected = True)

x = ['day 1', 'day 1', 'day 1', 'day 1', 'day 1', 'day 1',
     'day 2', 'day 2', 'day 2', 'day 2', 'day 2', 'day 2']

trace0 = go.Box(
    y=[0.2, 0.2, 0.6, 1.0, 0.5, 0.4, 0.2, 0.7, 0.9, 0.1, 0.5, 0.3],
    x=x,
    name='kale',
    marker=dict(
        color='#3D9970'
    )
)
trace1 = go.Box(
    y=[0.6, 0.7, 0.3, 0.6, 0.0, 0.5, 0.7, 0.9, 0.5, 0.8, 0.7, 0.2],
    x=x,
    name='radishes',
    marker=dict(
        color='#FF4136'
    )
)
trace2 = go.Box(
    y=[1, 3, 1, 9, 6, 6, 9, 1, 3, 6, 8, 5],
    x=x,
    name='carrots',
    marker=dict(
        color='#FF851B'
    ),
    yaxis='y2'
)
data = [trace0, trace1, trace2]
layout = go.Layout(
    yaxis=go.layout.YAxis(
        title='normalized moisture',
        range=[0, 1],
        zeroline=False
    ),
    yaxis2=go.layout.YAxis(
        side='right',
        overlaying='y',
        range=[0, 10],
        zeroline=False),
    boxmode='group'
)

fig = go.Figure(data=data, layout=layout)
iplot(fig)

newplot%20(15)

Hope that helps!
