Hi @Astha
Ah yes, that is a problem…
When I try to use the Interactive value filter widget like you intended:
…the value only gets filtered when I click “Apply”, close the plot window, and open it again. Not very useful, and it feels like a Knime bug to me.
Can someone from Knime confirm that this is a bug?
I recently had a somewhat similar problem and I posted it on the forum, but unfortunately I never got an answer: https://forum.knime.com/t/i-do-not-understand-nominal-row-filter-widget-behavior-in-a-component/31249/2
Actually, YOU solved my problem because indeed it does seem to work with the Plotly scatter node, even when it does not work with the standard Javascript scatter node! Thanks 
Best
Aswin
