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 (PLFLT_VECTOR(3plplot), input)
              A vector containing the x coordinates at which the function is evaluated.

       y (PLFLT_VECTOR(3plplot), input)
              A vector containing the y coordinates at which the function is evaluated.

       z (PLFLT_MATRIX(3plplot), input)
              A matrix containing function values to plot.  Should have dimensions of nx by ny.

       nx (PLINT(3plplot), input)
              Number of x values at which function is evaluated.

       ny (PLINT(3plplot), input)
              Number of y values at which function is evaluated.

       opt (PLINT(3plplot), 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 cmap1.  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 (PLFLT_VECTOR(3plplot), input)
              A vector containing the contour levels.

       nlevel (PLINT(3plplot), input)
              Number of elements in the clevel vector.
