Name: PGSUBP

Purpose: subdivide view surface into panels

Category: GRAPHICS

File: pgplot.src

Author: T.J. Pearson

Use: see description below.

Description:

SUBROUTINE PGSUBP (NXSUB, NYSUB)
INTEGER NXSUB, NYSUB

PGPLOT divides the physical surface of the plotting device (screen,
window, or sheet of paper) into NXSUB x NYSUB `panels'. When the
view surface is sub-divided in this way, PGPAGE moves to the next
panel, not the next physical page. The initial subdivision of the
view surface is set in the call to PGBEG. When PGSUBP is called,
it forces the next call to PGPAGE to start a new physical page,
subdivided in the manner indicated. No plotting should be done
between a call of PGSUBP and a call of PGPAGE (or PGENV, which calls
PGPAGE).

If NXSUB > 0, PGPLOT uses the panels in row order; if <0,
PGPLOT uses them in column order, e.g.,

NXSUB=3, NYSUB=2 NXSUB=-3, NYSUB=2

+-----+-----+-----+ +-----+-----+-----+
| 1 | 2 | 3 | | 1 | 3 | 5 |
+-----+-----+-----+ +-----+-----+-----+
| 4 | 5 | 6 | | 2 | 4 | 6 |
+-----+-----+-----+ +-----+-----+-----+

PGPLOT advances from one panels to the next when PGPAGE is called,
clearing the screen or starting a new page when the last panel has
been used. It is also possible to jump from one panel to another
in random order by calling PGPANL.

Arguments:
NXSUB (input) : the number of subdivisions of the view surface in
X (>0 or <0).
NYSUB (input) : the number of subdivisions of the view surface in
Y (>0).
