NAME

       plot3dcl - Magnitude colored plot surface with contour for z[x][y] with y index limits

SYNOPSIS

       plot3dcl(x, y, z, nx, ny, opt, clevel, nlevel, indexxmin, indexxmax, indexymin, indexymax)

DESCRIPTION

       When the implementation is completed this variant of plot3dc(3plplot) (see that function's
       documentation for more details) should be suitable for the case where the area of the x, y
       coordinate  grid  where  z  is  defined  can  be  non-rectangular.  The  implementation is
       incomplete so the last 4 parameters of  plot3dcl;  indexxmin,  indexxmax,  indexymin,  and
       indexymax;  are  currently ignored and the functionality is otherwise identical to that of
       plot3dc(3plplot).

       Redacted form: General: plot3dcl(x, y, z, opt, clevel,  indexxmin,  indexymin,  indexymax)
       Perl/PDL: Not available?

       This function is not used in any example.

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 the function is evaluated.

       ny (PLINT(3plplot), input)
              Number of y values at which the 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.

       indexxmin (PLINT(3plplot), input)
              The index value (which must be ≥ 0) that corresponds to the first x index  where  z
              is defined.

       indexxmax (PLINT(3plplot), input)
              The  index value (which must be ≤ nx) which corresponds (by convention) to one more
              than the last x index value where z is defined.

       indexymin (PLINT_VECTOR(3plplot), input)
              A vector containing y index values which all must be ≥ 0.   These  values  are  the
              first  y  index  where  z  is  defined  for  a particular x index in the range from
              indexxmin to indexxmax - 1. The dimension of indexymin is indexxmax.

       indexymax (PLINT_VECTOR(3plplot), input)
              A vector containing y index values which all must be ≤ ny. These values  correspond
              (by  convention)  to  one  more  than  the  last  y  index where z is defined for a
              particular x index in the range from indexxmin to indexxmax - 1.  The dimension  of
              indexymax is indexxmax.
