PLOT3D(3)                         PLplot API                         PLOT3D(3)



NAME
       plot3d - Plot 3-d surface plot

SYNOPSIS
       plot3d(x, y, z, nx, ny, opt, side)

DESCRIPTION
       Plots a three dimensional surface plot within the environment set up by
       plw3d(3).  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. The only difference between
       plmesh(3) and plot3d(3) is that plmesh(3) draws the bottom side of the
       surface, while plot3d(3) only draws the surface as viewed from the top.

       Redacted form: plot3d(x, y, z, opt, side)

       This function is used in examples 11,21.

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.


       side (PLBOOL, input)
              Flag to indicate whether or not ``sides'' should be draw on the
              figure.  If side is true sides are drawn, otherwise no sides are
              drawn.
