NAME

       plsurf3d - Plot shaded 3-d surface plot

SYNOPSIS

       plsurf3d(x, y, z, nx, ny, opt, clevel, nlevel)

DESCRIPTION

       Plots  a  three	dimensional shaded surface plot within the environment set up by plw3d(3plplot).  The surface is defined by the two-dimen-
       sional array z[nx][ny], the point z[i][j] being the value of the function at (x[i], y[j]).  Note that the points in arrays x and y  do  not
       need to be equally spaced, but must be stored in ascending order. For further details see the PLplot documentation.

       Redacted form: plsurf3d(x, y, z, opt, clevel)

       This function is not used in any examples.

ARGUMENTS

       x (PLFLT *, input)
	      Pointer to set of x coordinate values at which the function is evaluated.

       y (PLFLT *, input)
	      Pointer to set of y coordinate values at which the function is evaluated.

       z (PLFLT **, 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. FACETED +
	      SURF_CONT opt=FACETED: Network of lines is drawn connecting points at which function is defined.	opt=BASE_CONT: A contour  plot	is
	      drawn  at  the  base XY plane using parameters nlevel and clevel.  opt=SURF_CONT: A contour plot is drawn at the surface plane using
	      parameters nlevel and clevel.  opt=DRAW_SIDES: draws a curtain between the base XY plane and the borders of  the	plotted  function.
	      opt=MAG_COLOR: the surface is colored according to the value of Z; if MAG_COLOR is not used, then the default the surface is colored
	      according to the intensity of the reflected light in the	surface  from  a  light  source  whose	position  is  set  using  pllight-
	      source(3plplot).

       clevel (PLFLT *, input)
	      Pointer to the array that defines the contour level spacing.

       nlevel (PLINT, input)
	      Number of elements in the clevel array.

NAME

       plshade -  Shade individual region on the basis of value

SYNOPSIS

       plshade(a,  nx,	ny,  defined,  xmin, xmax, ymin, ymax, shade_min, shade_max, sh_cmap, sh_color, sh_width, min_color, min_width, max_color,
       max_width, fill, rectangular, pltr, pltr_data)

DESCRIPTION

       Shade individual region on the basis of value.  Use plshades(3plplot) if you want to shade a number of  regions	using  continuous  colors.
       plshade(3plplot)  is  identical	to plshade1(3plplot) except for the type of the first parameter. See plshade1(3plplot) for further discus-
       sion.

       Redacted form:  General: plshade(a, defined, xmin,  xmax,  ymin,  ymax,	shade_min,  shade_max,	sh_cmap,  sh_color,  sh_width,	min_color,
       min_width, max_color, max_width, fill, rectangular, pltr, pltr_data) Perl/PDL: Not available?

       This function is used in example 15.
