NAME¶
plot3dc - Magnitude colored plot surface with contour
SYNOPSIS¶
plot3dc(
x,
y,
z,
nx,
ny,
opt,
clevel,
nlevel)
DESCRIPTION¶
Aside from dropping the
side functionality this is a more powerful form
of
plot3d(3plplot): 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
plmeshc(3plplot). The only difference between
plmeshc (3plplot) and plot3dc(3plplot) is that
plmeshc(3plplot) draws the bottom side of the surface, while
plot3dc(3plplot) only draws the surface as viewed from the
top.
Redacted form: General:
plot3dc(x, y, z, opt, clevel) Perl/PDL: Not
available?
This function is used in example 21.
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 function is evaluated.
- ny (PLINT, input)
- Number of y values at which 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.
