NAME

6       plot3dc - Magnitude colored plot surface with contour
7

SYNOPSIS

9       plot3dc(x, y, z, nx, ny, opt, clevel, nlevel)
10

DESCRIPTION

12       Aside from dropping the side functionality this is a more powerful form
13       of plot3d(3plplot): the surface mesh can be colored accordingly to  the
14       current  z value being plotted, a contour plot can be drawn at the base
15       XY plane, and a curtain can be drawn between the plotted function  bor‐
16       der  and  the  base  XY  plane. The arguments are identical to those of
17       plmeshc(3plplot). The  only  difference  between  plmeshc(3plplot)  and
18       plot3dc(3plplot)  is that plmeshc(3plplot) draws the bottom side of the
19       surface, while plot3dc(3plplot) only draws the surface as  viewed  from
20       the top.

ARGUMENTS

29       x (PLFLT_VECTOR(3plplot), input)
30              A vector containing the x coordinates at which the  function  is
31              evaluated.
32
33       y (PLFLT_VECTOR(3plplot), input)
34              A  vector  containing the y coordinates at which the function is
35              evaluated.
36
37       z (PLFLT_MATRIX(3plplot), input)
38              A matrix containing function values to plot.  Should have dimen‐
39              sions of nx by ny.
40
41       nx (PLINT(3plplot), input)
42              Number of x values at which function is evaluated.
43
44       ny (PLINT(3plplot), input)
45              Number of y values at which function is evaluated.
46
47       opt (PLINT(3plplot), input)
48              Determines the way in which the surface is represented. To spec‐
49              ify more than one option just add the options, e.g.  DRAW_LINEXY
50              +  MAG_COLOR  opt=DRAW_LINEX  :  Lines  are drawn showing z as a
51              function of x for each value of y[j] .  opt=DRAW_LINEY  :  Lines
52              are  drawn showing z as a function of y for each value of x[i] .
53              opt=DRAW_LINEXY : Network of lines is drawn connecting points at
54              which  function  is  defined.   opt=MAG_COLOR : Each line in the
55              mesh is colored according to the  z  value  being  plotted.  The
56              color is used from the current cmap1.  opt=BASE_CONT : A contour
57              plot is drawn at the base XY plane using parameters  nlevel  and
58              clevel.   opt=DRAW_SIDES  :  draws a curtain between the base XY
59              plane and the borders of the plotted function.
60
61
62       clevel (PLFLT_VECTOR(3plplot), input)
63              A vector containing the contour levels.
64
65       nlevel (PLINT(3plplot), input)
66              Number of elements in the clevel vector.
