Thanks Zach,
That simple little example makes more sense than the manual page did.
Perhaps it's just late.
I appreciate it.

I've got some verts I stole from the internet that draws an upward arrow
(or a down arrow), but I need to draw an arrow to the right or to the
left. But I don't really understand verts and how they work.
arrowup_verts = [[0.,0.], [-1., -1], [0.,0.], [0.,-2.],[0.,0.], [1,-1]]
arrowdown_verts = [[0.,0.], [-1., 1], [0.,0.], [0.,2.],[0.,0.], [1, 1]]
plot them like...
scatter(1,1,s=100, marker=None, verts=arrowup_verts)
Can someone make me new verts for the right and left arrow? Then, maybe
tomorrow, explain how I was supposed to know what to do.
Draw a line from (0,0) to (-1, -1) on the X-Y plane, and then to (0,0) again,
and then continue so forth for all the (x,y) pairs in arrowup_verts. You will
notice they form a nice little arrow pointing up. (At some point in this
process, you should note that verts is short for vertices. As in vertices
of a polygon or poly-line.)
It would seem that the origin of the verts coordinate system is translated
to the (x,y) data position at which each marker is plotted.
This should give you, I presume, sufficient information to figure out your
own left and right arrows, no? Or any other shape you should care to plot...

Thanks y'all
