I'm trying to plot some vector data in matlab using the quiver function (full disclosure, I'm actually using m_quiver from the m_maps toolbox).

What I want is to set each individual arrow color to be relative to its direction, e.g. north being red, south being blue. Is there a way to do this? I'm picturing something like the CData option with scatter plots!

Hi Aidan, Did you find something to do this? I am interested in the same sort of plotting.

I gave up... At the moment I'm just using quiver_mc (which is an awesome function) and letting the magnitude set the color. -Sorry!

Great! Although this seems to define colour by magnitude and not direction. My issue is the arrow directions are slightly unclear because of the density.
