Is there a way to customize the color of the trace based on some values(e.g. I have concentrations of pollutants along the track). Thanks.
How can I have the trace_colour the same colour as the associated path_colour when I have multiple animals on the same map? I have seen maps that are that way (same trace_colour as path_colour for each animal) but I could not find to way to do it. I would really appreciate some help, many thanks !
I'm also hoping to allow the traces to maintain the same color as the associated path, and ideally reduce the alpha. Any idea how to do this?
Hi, frames_spatial() has a "trace_colour" argument which defaults to white but setting trace_colour to a vector of colours (as can be done for path_colours = c("red", "green", "blue") doesn't work. Note the "path colours" argument is plural but "trace_colour" is singular, so this feature works for an animation of one animal's movements but not for multiple animals. Ideally, "path_colours" and "trace_colours" could be set to the same vector of colours, perhaps in a future release?
