IIRC, the backends that matplotlib uses (Gtk, Agg, etc.) only support a
single color per line, so breaking up the line into different
segments/points is really your only option. Instead of scatter, you can
break up your line into separate sections and have them colormapped for you,
using a LineCollection.
