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)

       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.
