Some stream reaches host more than one fish species. Is there a way to color
those segments with multiple colors, one for each species? I'm thinking of
the equivalent of a dashed line with adjacent segments colored for each
species and segment sizes based on the number of species and length of
stream reach.
Alternate solutions are equally good.
TIA,
Rich

v.colors comes to mind.

Markus,
I thought of this and assumed that it would color entire lines based on a
category or attribute. When a river segment has reported to host multiple
fish species that segment could display only a single color based on the
range of the color scale.
Creating maps for the distribution of the nine species/runs I determined
that lower-order streams would be too short to effectively display multiple
colors, one for each fish observed there. I concluded that one-fish, one-map
is the way to go. Readers of the document can page back and forth comparing
stream/river reaches for the fish reported to be found there.
Thanks very much,
Rich
