Mark, Petr,
I would like to plot the line which interconnects the GPS track points
(latitude and longitude coordinates) recorded by GPS receiver. It is
not so difficult. What I am not able to do is to change the color of
the line according to the speed reached on the way from point to
point. I would like to use the color of the line to differentiate the
speed as following:speed <=50km/h
speed >50 and <=90km/h
speed >90 and <=130km/h
speed >130km/h
It can be done, but not with a simple plot command. See the attached demo; I think it is similar to what you want to do.
