xopt
(const char *, input)
Pointer to character string specifying options for the x axis.
The string can include any combination of the following letters
(upper or lower case) in any order:
b: Draws axis at base, at height
z=zmin where
zmin is defined
by call to plw3d. This character must be specified in
order to use any of the other options.
f: Always use fixed point numeric labels.
i: Inverts tick marks, so they are
drawn downwards, rather than upwards.
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.
n: Writes numeric labels at major tick
intervals.
s: Enables subticks between major
ticks, only valid if t is also
specified.
t: Draws major ticks.
u: If this is specified, the text
label for the axis is written under the axis.
xlabel
(const char *, input)
Pointer to character string specifying text label for the x
axis. It is only drawn if u is in the
xopt string.
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 the y axis.
The string is interpreted in the same way as
xopt.
ylabel
(const char *, input)
Pointer to character string specifying text label for the y
axis. It is only drawn if u is in the
yopt string.
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.
zopt
(const char *, input)
Pointer to character string specifying options for the z axis.
The string can include any combination of the following letters
(upper or lower case) in any order:
b: Draws z axis to the left of the
surface plot.
c: Draws z axis to the right of the
surface plot.
d: Draws grid lines parallel to the
x-y plane behind the figure. These lines are not drawn
until after plot3d or plmesh are called because of
the need for hidden line removal.
f: Always use fixed point numeric labels.
i: Inverts tick marks, so they are
drawn away from the center.
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 on the right-hand vertical axis.
n: Writes numeric labels at major tick
intervals on the left-hand vertical axis.
s: Enables subticks between major
ticks, only valid if t is also
specified.
t: Draws major ticks.
u: If this is specified, the text
label is written beside the left-hand axis.
v: If this is specified, the text
label is written beside the right-hand axis.
zlabel
(const char *, input)
Pointer to character string specifying text label for the z
axis. It is only drawn if u or
v are in the
zopt string.
ztick
(PLFLT, input)
World coordinate interval between major ticks on the z axis.
If it is set to zero, PLplot automatically generates a suitable
tick interval.
nzsub
(PLINT, input)
Number of subintervals between major z axis ticks for minor
ticks. If it is set to zero, PLplot automatically generates a
suitable minor tick interval.
