Arrowhead styling #15

Open kjordahl opened 9 years ago

kjordahl commented 9 years ago

PR #12 introduced arrow tails for direction indication. There is an arrowHeadSize parameter to scale the arrow barbs, but we may want some more parameters to control styling.

Some potential styling parameters:

Most likely these would not be available to the end user, but for development purposes and tweaking the final look.

Sweep angle handled by #20

johntyree commented 9 years ago

If we choose absolute scaling what are we implying? That the arrow head will change size relative to the shaft, but not relative to the map?

kjordahl commented 9 years ago

@johntyree Yes: the arrowheads would be the same size for all vectors in view, regardless of magnitude. That's how matplotlib's quiver works. I think we can defer that for now.

johntyree commented 9 years ago

Ok sure. It wouldn't be particularly hard to change, at any rate.

Barb location handled in #24.
