Description
I want to be able to set different colors for different sections of a line from a line chart. For example, I want to have a red line from spots 1 to 10, a blue line from spots 10 to 40 etc.
Right now I can only set one single color or a gradient for the entire line. Is there a more low-level way of achieving what I need?
How I see this working is having a colors param that is the same length as the spots list and contains a color for each spot.

Research direction
Start by locating the line-chart API and the existing single-color or gradient configuration. Trace how spots are rendered into line sections and define how per-spot colors should affect the requested ranges. Done means distinct sections can use distinct colors while existing single-color and gradient behavior continues to work, with coverage for the requested ranges.
