I have 15 subplots with 4 datasets on each of them (2 box and 2 scatter x 15).  
Trying to have the scatter plots on a secondary y axis (and set their ranges), but can’t seem to figure it out in plotly js.  
Managed to get it running on python with the use of fig.update\_yaxes(range=##,secondary\_y=True,row=row,col=col)  
Does anyone know how to fun this in javascript ? aiming for output as figure below:  
Many thanks

The codepen in [Subplots w/multiple y-axes](https://community.plotly.com/t/subplots-w-multiple-y-axes/28352/2) presents one way of doing this that might work for your use case.
