Modify axes range using plotly

A solution that works with subplots is:

fig.update_yaxes(range=[0, 0.4], row=1, col=1)

import plotly.graph_objs as go    
layout = go.Layout(
        yaxis=dict(
            range=[0, 0.4]
        )
    )

    Dataframe.iplot(kind='bubble', x='branch', y='retention', size='active_users', text='active_users',
                 xTitle='', yTitle='Retention',
                 filename='cufflinks/PlotName', layout = layout)

This will do the trick.
