thanks, Rossko.
I am trying to think about what I'm doing, but I'm working at the
severe disadvantage of not having a clue about what I am actually
doing. I appreciate everybody's patience on this one. I've got this
far by adapting lots of code from the excellent examples out there,
lots of trial and lots more error.
but to extend the polyline category to the arrow making routine, in my
twisted idea of how this works, I would add:
var category = lines[a].getAttribute("category");
to the createArrow function
then replace:
midLineArrows(pts)
with:
midLineArrows(pts,category)
but that just completely freaks the map out.
I guess I'm missing something minor but key, but like I say I have no
idea what it may be...
