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.
plmesh
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: plmeshc(x, y, z, opt, clevel)
This function is used in example 11.
