I have a plotly line chart connecting points. Basically, for t=t_0, I want all points with x>=t to have blue color and a description on hover: "Blue", and all points with x<t to be grey with description on hover: "Grey". Any ideas how to achieve this? Thank you in advance!
N.B: Please, don't mark this question as duplicate, since the other one that I got reference to last time is a huge question filled with data. Having a clear answer to this one would be of a great use for other users as well.
