NAME

       plmtex3 - Write text relative to viewport boundaries in 3D plots.

SYNOPSIS

       plmtex3(side, disp, pos, just, text)

DESCRIPTION

       Writes  text  at  a  specified  position  relative  to the viewport boundaries.	Text may be written inside or outside the viewport, but is
       clipped at the subpage 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 position of the reference point rela-
       tive to the viewport is set by disp and pos.

       Redacted form: plmtex3(side, disp, pos, just, text)

       This function is used in example 28.

ARGUMENTS

       side (const char *, input)
	      Specifies the side of the viewport along which the text is to be written. The string should contain one or  more	of  the  following
	      characters:  [xyz][ps][v].   Only  one  label is drawn at a time, i.e. xyp will only label the X axis, not both the X and Y axes. x:
	      Label the X axis.  y: Label the Y axis.  z: Label the Z axis.  p: Label the primary axis. For Z this is the leftmost Z axis.  For  X
	      it is the axis that starts at y-min. For Y it is the axis that starts at x-min.  s: Label the secondary axis.  v: Draw the text per-
	      pendicular to the axis.

       disp (PLFLT, input)
	      Position of the reference point of string, measured outwards from the specified viewport edge in	units  of  the	current  character
	      height.  Use negative disp to write within the viewport.

       pos (PLFLT, input)
	      Position of the reference point of string along the specified edge, expressed as a fraction of the length of the edge.

       just (PLFLT, 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 (const char *, input)
	      The string to be written out.

NAME

       plcalc_world - Calculate world coordinates and corresponding window index from relative device coordinates

SYNOPSIS

       plcalc_world(rx, ry, wx, wy, window)

DESCRIPTION

       Calculate world coordinates, wx and wy, and corresponding window index from relative device coordinates, rx and ry.

       Redacted form:  General: plcalc_world(rx, ry, wx, wy, window) Perl/PDL: Not available?

       This function is used in example 31.

ARGUMENTS

       rx (PLFLT, input)
	      Input relative device coordinate (ranging from 0. to 1.) for the x coordinate.

       ry (PLFLT, input)
	      Input relative device coordinate (ranging from 0. to 1.) for the y coordinate.

       wx (PLFLT *, output)
	      Pointer to the returned world coordinate for x corresponding to the relative device coordinates rx and ry.

       wy (PLFLT *, output)
	      Pointer to the returned world coordinate for y corresponding to the relative device coordinates rx and ry.

       window (PLINT *, output)
	      Pointer  to the returned last defined window index that corresponds to the input relative device coordinates (and the returned world
	      coordinates).  To give some background on the window index, for each page the initial window index is set to  zero,  and	each  time
	      plwind(3plplot)  is  called  within  the page, world and device coordinates are stored for the window and the window index is incre-
	      mented.  Thus, for a simple page layout with non-overlapping viewports and one window per viewport, window corresponds to the  view-
	      port  index (in the order which the viewport/windows were created) of the only viewport/window corresponding to rx and ry.  However,
	      for more complicated layouts with potentially overlapping viewports and possibly more than one window (set of world coordinates) per
	      viewport,  window  and  the corresponding output world coordinates corresponds to the last window created that fulfils the criterion
	      that the relative device coordinates are inside it.  Finally, in all cases where the  input  relative  device  coordinates  are  not
	      inside any viewport/window, then window is set to -1.
