Hi,
I have a set of points (lat, long) which I eould like to plot as a trajectory path. on top of that, I'd like to add an arrow for the direction of the movement.
How can I do this?
Note, I'm using MATLAB R14
Note2: I can have small set size (1000 points) and can have huge set size (hundred thousand of points)

I do use quiver, but It barely seen in figure.
When I do a copy of a figure to populate it in word, instead of arrows I see big black point on the trace :(

Try exportgraphics or copygraphics
Try annotation instead of quiver. Look into options that let you control the size of the arrow's parts.

annottation requires tha xand y will be between 0 and 1, however, I'm using lat long which is not so between 0 and 1
the exportgraphics or copygraphics not supported by MATLAB R14

Ok, can you upgrade? And did you check out the options for changing the appearance of the arrows?
