Is your feature request related to a problem? Please describe.
Right now, we have to use discrete colors in the chart options for lines or scatter. There are cases where having a continuous scale would be more beneficial for end user readability

Describe the solution you'd like
I would like to be able to use a continuous color scale to color the lines on the chart so the chart is more readable for the consumers.

Describe alternatives you've considered
I am currently building this chart through excel and python to clarify the data output

How important is this feature to you?
quite important, A lot of the cohort based charts would be massively improved with this feature and people would be able to read them at a glance. We lose a lot of people looking at the chart in its current state and that is just more work for our data team.
