Aside from dropping the side
functionality this is a more powerful form of
:
the surface mesh can be colored accordingly to the current z value being plotted,
a contour plot can be drawn at the base XY plane, and a curtain can be drawn between
the plotted function border and the base XY plane.
The arguments are identical to those of plot3d
. The only difference between
plmeshc
plmeshc
and plot3dc
is that plmeshc
draws the bottom side of the surface, while
plot3dc
only draws the surface as viewed from the top.
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
values at
which function is evaluated.
x
ny
(PLINT
, input)
Number of
values at
which function is evaluated.
y
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
: Lines
are drawn showing
opt
=DRAW_LINEX
as a function
of z
for each
value of x
.
y
[j]
: Lines
are drawn showing
opt
=DRAW_LINEY
as a function
of z
for each
value of y
.
x
[i]
: Network
of lines is drawn connecting points at which function is
defined.
opt
=DRAW_LINEXY
: 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
=MAG_COLOR
: A contour
plot is drawn at the base XY plane using parameters
opt
=BASE_CONTnlevel
and clevel
.
: draws a curtain
between the base XY plane and the borders of the plotted function.
opt
=DRAW_SIDES
clevel
(const PLFLT *
, input)
Pointer to the array that defines the contour level spacing.
nlevel
(PLINT
, input)
Number of elements in the clevel
array.
Redacted form:
General: plot3dc(x, y, z, opt, clevel)
