CODE EXAMPLE FOR PYTHON

plotly two y axis bar chart grouped

'''I hope the code below, based on zoo example, will be self-explanatory, 
however you have to set yaxis and offsetgroup parameters in go.Bar() object, 
and also yaxis2 parameter in layout parameter of go.Figure() object properly. 
The code is following:'''

import plotly.graph_objects as go
animals=['giraffes', 'orangutans', 'monkeys']

fig = go.Figure(
    data=[
        go.Bar(name='SF Zoo', x=animals, y=[200, 140, 210], yaxis='y', offsetgroup=1),
        go.Bar(name='LA Zoo', x=animals, y=[12, 18, 29], yaxis='y2', offsetgroup=2)
    ],
    layout={
        'yaxis': {'title': 'SF Zoo axis'},
        'yaxis2': {'title': 'LA Zoo axis', 'overlaying': 'y', 'side': 'right'}
    }
)

# Change the bar mode
fig.update_layout(barmode='group')
fig.show()
