NAME

       plptex3 - Write text inside the viewport of a 3D plot

SYNOPSIS

       plptex3(wx, wy, wz, dx, dy, dz, sx, sy, sz, just, text)

DESCRIPTION

       Writes  text at a specified position and inclination and with a specified shear within the
       viewport.  Text is clipped at the viewport boundaries.  The reference point  of  a  string
       lies  along a line passing through the string at half the height of a capital letter.  The
       position of the reference point along this line is determined by just, and  the  reference
       point  is  placed  at world coordinates (wx, wy, wz)  within the viewport. The inclination
       and shear of the string is specified in terms of differences of world  coordinates  making
       it easy to write text parallel to a line in a graph.

       Redacted form: plptex3(x, y, z, dx, dy, dz, sx, sy, sz, just, text)

       This function is used in example 28.

ARGUMENTS

       wx (PLFLT(3plplot), input)
              x world coordinate of reference point of string.

       wy (PLFLT(3plplot), input)
              y world coordinate of reference point of string.

       wz (PLFLT(3plplot), input)
              z world coordinate of reference point of string.

       dx (PLFLT(3plplot), input)
              Together  with  dy  and  dz  ,  this  specifies the inclination of the string.  The
              baseline of the string is parallel to a line joining (x, y,  z)   to  (x+dx,  y+dy,
              z+dz) .

       dy (PLFLT(3plplot), input)
              Together with dx and dz, this specifies the inclination of the string.

       dz (PLFLT(3plplot), input)
              Together with dx and dy, this specifies the inclination of the string.

       sx (PLFLT(3plplot), input)
              Together  with  sy  and sz , this specifies the shear of the string.  The string is
              sheared so that the characters are vertically parallel to a line joining (x, y,  z)
              to (x+sx, y+sy, z+sz) . If sx = sy = sz = 0.)  then the text is not sheared.

       sy (PLFLT(3plplot), input)
              Together with sx and sz, this specifies shear of the string.

       sz (PLFLT(3plplot), input)
              Together with sx and sy, this specifies shear of the string.

       just (PLFLT(3plplot), input)
              Specifies the position of the string relative to its reference point.  If just=0. ,
              the reference point is at the left and if just=1. , it  is  at  the  right  of  the
              string.  Other values of just give intermediate justifications.

       text (PLCHAR_VECTOR(3plplot), input)
              A UTF-8 character string to be written out.
