I regularly use Octave to generate high quality plots
for papers. Now I am trying to put two separate
plots in one figure.
Plot A would use the commands, scales, titles, etc.,
that I regularly use:
... calculate ...
system('rm plot_name.ps');
__gnuplot_set__ terminal postscript ...
__gnuplot_set__ output 'plot_name.ps'
__gnuplot_set__ xrange [0:2.5]
...
plot( x1, y1, '-1' \
,x2, y2, '+2' \
)
system('rm plot_name.ps');
__gnuplot_set__ output 'plot_name.ps'
replot
closeplot
and would generate curves running diagonally across
the plotting area.
Plot B is to be a simple vector polygon in an unused
corner to the plotting area showing:
A horizontal vector in the negative x-direction
plus
a vertical vector in the positive y-direction
plus
two horizontal vectors in the positive x-direction
equal to
a resultant vector running from the tail of the
first vector to the head of the fourth.
The equal horizontal and vertical scales of the vectors
are unrelated to the x- and y-scales of the other curves
(different units and ranges).
Can Octave/Gnuplot handle this? I haven't been able to
find similar examples.
Or should I try drawing two separate plots and then
printing one on top of the other?
Thanks,
ms
