NAME¶
plot3dcl - Magnitude colored plot surface with contour for z[x][y] with y
index limits
SYNOPSIS¶
plot3dcl(
x,
y,
z,
nx,
ny,
opt,
clevel,
nlevel,
indexxmin,
indexxmax,
indexymin,
indexymax)
DESCRIPTION¶
When the implementation is completed this variant of
plot3dc(3plplot)
(see that function's documentation for more details) should be suitable for
the case where the area of the
x,
y coordinate grid where
z is defined can be non-rectangular. The implementation is incomplete
so the last 4 parameters of plot3dcl;
indexxmin,
indexxmax,
indexymin, and
indexymax; are currently ignored and the
functionality is otherwise identical to that of
plot3dc(3plplot).
Redacted form: General:
plot3dcl(x, y, z, opt, clevel, indexxmin, indexymin,
indexymax) Perl/PDL: Not available?
This function is not used in any example.
ARGUMENTS¶
- x (const PLFLT *, input)
- Pointer to set of x coordinate values at which the function is
evaluated.
- y (const PLFLT *, input)
- Pointer to set of y coordinate values at which the function is
evaluated.
- z (const PLFLT * const *, input)
- Pointer to a vectored two-dimensional array with set of function
values.
- nx (PLINT, input)
- Number of x values at which the function is evaluated.
- ny (PLINT, input)
- Number of y values at which the function is evaluated.
- opt (PLINT, input)
- Determines the way in which the surface is represented. To specify more
than one option just add the options, e.g. DRAW_LINEXY + MAG_COLOR
opt=DRAW_LINEX: Lines are drawn showing z as a function of
x for each value of y[j]. opt=DRAW_LINEY: Lines are
drawn showing z as a function of y for each value of
x[i]. opt=DRAW_LINEXY: Network of lines is drawn connecting
points at which function is defined. opt=MAG_COLOR: Each line in
the mesh is colored according to the z value being plotted. The color is
used from the current color map 1. opt=BASE_CONT: A contour plot is
drawn at the base XY plane using parameters nlevel and
clevel. opt=DRAW_SIDES: draws a curtain between the base XY
plane and the borders of the plotted function.
- clevel (const PLFLT *, input)
- Pointer to the array that defines the contour level spacing.
- nlevel (PLINT, input)
- Number of elements in the clevel array.
- indexxmin (PLINT, input)
- The index value (which must be ≥ 0) that corresponds to the first
x index where z is defined.
- indexxmax (PLINT, input)
- The index value (which must be ≤ nx) which corresponds (by
convention) to one more than the last x index value where z
is defined.
- indexymin (const PLINT *, input)
- Array of y index values which all must be ≥ 0. These values
are the first y index where z is defined for a particular
x index in the range from indexxmin to indexxmax - 1.
The dimension of indexymin is indexxmax.
- indexymax (const PLINT *, input)
- Array of y index values which all must be ≤ ny. These
values correspond (by convention) to one more than the last y index
where z is defined for a particular x index in the range
from indexxmin to indexxmax - 1. The dimension of
indexymax is indexxmax.
