Howdy: Does anyone know of a way to plot velocity vectors using MI? I've looked into the 'arrow' routine, and it isn't quite right. We're plotting GPS velocity vectors on geological maps and doing it mostly by hand right now. Ideally, a routine would take as input the coordinates of the root of the vector but use the paper scale for the vector length (i.e., one would give the routine 1 inch for the vector easting and 0.5 for the vector northing). Optionally, a label could be plotted at the base of the vector. There is a C++ routine called psvelomeca used with a package called GMT (Generic Mapping Tools, http://imina.soest.hawaii.edu/gmt/), but I'd like to avoid doing the translation if something like this is already available. Thanks in advance.
