Using code based on:

> How to draw lines, great circles, and contours on maps in Python.

Need the lines drawn in flight\_paths[] as gradient from point A to B, for example from red to green.  
Cant figure it out. Help.

Hi @jrp,

Variable coloring within lines isn’t support in `scattergeo` traces. For completeness, it’s also not possible with 2D `scatter` or `scattergl` traces, but it is possible in 3D `scatter3d` traces.

So the best you could do would be a discrete gradient made up of multiple traces. If you go this route, for performance I’d recommend creating a single trace for each discrete color across all flights, where `nan` values separate individual flights. Feel free to post a simple example if you’re interested in working through this approach.
