NAME

       plpoin3 - Plot a glyph at the specified 3D points

SYNOPSIS

       plpoin3(n, x, y, z, code)

DESCRIPTION

       Plot  a	glyph  at  the specified 3D points.  (This function is largely superseded by plstring3(3plplot) which gives access to many[!] more
       glyphs.) Set up the call to this function similar to what is done for plline3(3plplot). code=-1 means try to just draw a point.	Right  now
       it's  just  a  move and a draw at the same place.  Not ideal, since a sufficiently intelligent output device may optimize it away, or there
       may be faster ways of doing it.	This is OK for now, though, and offers a 4X speedup over drawing a Hershey font "point" (which is actually
       diamond	shaped	and therefore takes 4 strokes to draw).  If 0 < code < 32, then a useful (but small subset) of Hershey symbols is plotted.
       If 32 <= code <= 127 the corresponding printable ASCII character is plotted.

       Redacted form: plpoin3(x, y, z, code)

       This function is not used in any example.

ARGUMENTS

       n (PLINT, input)
	      Number of points in the x and y arrays.

       x (PLFLT *, input)
	      Pointer to an array with X coordinates of points.

       y (PLFLT *, input)
	      Pointer to an array with Y coordinates of points.

       z (PLFLT *, input)
	      Pointer to an array with Z coordinates of points.

       code (PLINT, input)
	      Hershey symbol code (in "ascii-indexed" form with -1 <= code <= 127) corresponding to a glyph to be plotted at each of the n points.

NAME

       plmesh - Plot surface mesh

SYNOPSIS

       plmesh(x, y, z, nx, ny, opt)

DESCRIPTION

       Plots  a  surface mesh within the environment set up by plw3d(3plplot).	The surface is defined by the two-dimensional 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.	The parameter opt controls the way in which the surface is displayed.  For further details see the
       PLplot documentation.

       Redacted form: plmesh(x, y, z, opt)

       This function is used in example 11.

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: 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.
