From gnuplot's help:
The vectors style draws a vector from (x,y) to (x+xdelta,y+ydelta).
Thus it requires four columns of data. It also draws a small arrowhead
at the end of the vector.
plot 'file.dat' using 1:2:3:4 with vectors head filled lt 2
Here's a gnuplot example of a vector field plot:
If you don't find out how to do it with xplt, try gnuplot.py to drive
gnuplot to do what you want.
