Hi,
If you need something like this
you can do it with Python View node (Plotly express) … you can have more then 2 y axes … Look here Multiple Axes | Python | Plotly
In KNIME is something like this 2 y axes.knwf (1.1 MB)
P.S. : For this you must have instaled (Anaconda) libraries Plotly express and Kaleido
Hope this helps
Regards
Andrej
