 The quiver problem on the current Debian octaveforge
 confuses me.

 The following does not work:

 gplot M w v t ""

 The following works:

 gplot '/tmp/octXXXXX' w v t ""

 where /tmp/octXXXXX contains the contents of the 4column M.
I tried saving some 4column data to a file and using
plot 'foo.dat' w v t ""
and gnuplot complained:
gnuplot> plot 'foo.dat' w v t ""
^
expecting 'lines', 'points', 'linespoints', 'dots', 'impulses',
'yerrorbars', 'xerrorbars', 'xyerrorbars', 'steps', 'fsteps',
'histeps', 'filledcurves', 'boxes', 'boxerrorbars',
'boxxyerrorbars',
'vectors', 'financebars', 'candlesticks', 'errorlines',
'xerrorlines',
'yerrorlines', 'xyerrorlines', 'pm3d'
so what is a valid gnuplot plotting command that works so I can
understand what you are trying to plot.
