NAME
plbox - Draw a box with axes, etc
SYNOPSIS
plbox(xopt, xtick, nxsub, yopt, ytick, nysub)
DESCRIPTION
Draws a box around the currently defined viewport, and labels it with world coordinate
values appropriate to the window. Thus plbox(3plplot) should only be called after
defining both viewport and window. The character strings xopt and yopt specify how the
box should be drawn as described below. If ticks and/or subticks are to be drawn for a
particular axis, the tick intervals and number of subintervals may be specified
explicitly, or they may be defaulted by setting the appropriate arguments to zero.
Redacted form: General: plbox(xopt, xtick, nxsub, yopt, ytick, nysub) Perl/PDL:
plbox(xtick, nxsub, ytick, nysub, xopt, yopt)
This function is used in examples 1,2,4,6,6-12,14-18,21,23-26,29.
ARGUMENTS
xopt (const char *, input)
Pointer to character string specifying options for horizontal axis. The string can
include any combination of the following letters (upper or lower case) in any
order: a: Draws axis, X-axis is horizontal line (y=0), and Y-axis is vertical line
(x=0). b: Draws bottom (X) or left (Y) edge of frame. c: Draws top (X) or right
(Y) edge of frame. d: Plot labels as date / time. Values are assumed to be
seconds since the epoch (as used by gmtime). f: Always use fixed point numeric
labels. g: Draws a grid at the major tick interval. h: Draws a grid at the minor
tick interval. i: Inverts tick marks, so they are drawn outwards, rather than
inwards. l: Labels axis logarithmically. This only affects the labels, not the
data, and so it is necessary to compute the logarithms of data points before
passing them to any of the drawing routines. m: Writes numeric labels at major
tick intervals in the unconventional location (above box for X, right of box for
Y). n: Writes numeric labels at major tick intervals in the conventional location
(below box for X, left of box for Y). o: Use custom labelling function to generate
axis label text. The custom labelling function can be defined with the
plslabelfunc(3plplot) command. s: Enables subticks between major ticks, only valid
if t is also specified. t: Draws major ticks. u: Exactly like "b" except don't
draw edge line. w: Exactly like "c" except don't draw edge line. x: Exactly like
"t" (including the side effect of the numerical labels for the major ticks) except
exclude drawing the major and minor tick marks.
xtick (PLFLT, input)
World coordinate interval between major ticks on the x axis. If it is set to zero,
PLplot automatically generates a suitable tick interval.
nxsub (PLINT, input)
Number of subintervals between major x axis ticks for minor ticks. If it is set to
zero, PLplot automatically generates a suitable minor tick interval.
yopt (const char *, input)
Pointer to character string specifying options for vertical axis. The string can
include any combination of the letters defined above for xopt, and in addition may
contain: v: Write numeric labels for vertical axis parallel to the base of the
graph, rather than parallel to the axis.
ytick (PLFLT, input)
World coordinate interval between major ticks on the y axis. If it is set to zero,
PLplot automatically generates a suitable tick interval.
nysub (PLINT, input)
Number of subintervals between major y axis ticks for minor ticks. If it is set to
zero, PLplot automatically generates a suitable minor tick interval.
