NAME¶
plaxes - Draw a box with axes, etc. with arbitrary origin
SYNOPSIS¶
plaxes(
x0,
y0,
xopt,
xtick,
nxsub,
yopt,
ytick,
nysub)
DESCRIPTION¶
Draws a box around the currently defined viewport with arbitrary
world-coordinate origin specified by
x0 and
y0 and labels it
with world coordinate values appropriate to the window. Thus
plaxes(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:
plaxes(x0, y0, xopt, xtick, nxsub, yopt, ytick,
nysub) Perl/PDL:
plaxes(x0, y0, xtick, nxsub, ytick, nysub, xopt,
yopt)
This function is not used in any examples.
ARGUMENTS¶
- x0 (PLFLT, input)
- World X coordinate of origin.
- y0 (PLFLT, input)
- World Y coordinate of origin.
- 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 labeling function to generate axis label text. The
custom labeling function can be defined with the plslabelfuncplslabelfunc;
command. s: Enables subticks between major ticks, only valid if t is also
specified. t: Draws major ticks.
- 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.
