Plot speed along trajectory

https://datashader.org/user_guide/Trajectories.html describes how to plot trajectories. However, it does not mention if it is possible to use additional columns or derived attributes (such as speed between consecutive locations) to color the trajectory.

http://holoviews.org/reference/elements/matplotlib/Path.html shows how to color a path according to a given column but I don’t know if this information can somehow be transferred to datashader.
