How can I plot a list of points in space where the points are colored by their height?
The following code:
biglist = [(0, 0, 12), (0, 1, 19), (0, 2, 24), (0, 3, 30), (0, 4, 33), (0, 5, 35),
(0, 6, 38), (0, 7, 40), (0, 8, 41), (0, 9, 43), (0, 10, 44), (0, 11,
44), (0, 12, 44), (0, 13, 44)]
cm = colormaps.autumn
cf = lambda (x,y,z): z/100 % 1
list_plot3d(biglist, color=(cm,cf), point_list=True)
produces the following error:
