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.
