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.
