Hover over lines in parallel coordinate chart

Is there a way to add hovering text over the lines in the parallel coordinate chart? Once I set my constraints, I’d like to hover over the filtered lines and see their labels or IDs. Is hover different in parcoords than in other charts? I can’t make it work.


Hi @lkchauhan, this isn’t currently possible but it’s a nice idea. Feel free to open a feature request for the Plotly.js project (

Hi @jmmease, I will add the issue. I’d like to work on it if someone can guide me on some of the pieces of the code. Thanks
