I am trying to color points on a map by a certain dimension (say the speed of a ship along its route). However, the color range automatically uses discrete values of this dimension, which results in a “one value = one color” . There is no continuous shade from a color to another with respect to the ship’s speed. The feature seems to be working with tree maps but not in map plots.
Is it an expected feature, or am I missing something ?
Thanks for your help !
