NAME

       plaxes - Draw a box with axes, etc. with arbitrary origin

SYNOPSIS

       plaxes(x0, y0, xopt, xtick, nxsub, yopt, ytick, nysub)

DESCRIPTION

       Draws  a box around the currently defined viewport with arbitrary world-coordinate origin specified by x0
       and y0 and labels it with world coordinate values appropriate to the window.  Thus plaxes(3plplot) should
       only be called after defining both viewport and window.  The character strings xopt and yopt specify  how
       the  box  should  be drawn as described below.  If ticks and/or subticks are to be drawn for a particular
       axis, the tick intervals and number of subintervals may be specified explicitly, or they may be defaulted
       by setting the appropriate arguments to zero.

       Redacted form:  General: plaxes(x0, y0, xopt, xtick, nxsub, yopt, ytick, nysub) Perl/PDL: plaxes(x0,  y0,
       xtick, nxsub, ytick, nysub, xopt, yopt)

       This function is not used in any examples.

ARGUMENTS

       x0 (PLFLT, input)
              World X coordinate of origin.

       y0 (PLFLT, input)
              World Y coordinate of origin.

       xopt (const char *, input)
              Pointer  to  character  string specifying options for horizontal axis.  The string can include any
              combination of the following letters (upper or lower case) in any order: a: Draws axis, X-axis  is
              horizontal line (y=0), and Y-axis is vertical line (x=0).  b: Draws bottom (X) or left (Y) edge of
              frame.   c:  Draws top (X) or right (Y) edge of frame.  d: Plot labels as date / time.  Values are
              assumed to be seconds since the epoch  (as used by gmtime).  f:  Always use  fixed  point  numeric
              labels.   g: Draws a grid at the major tick interval.  h: Draws a grid at the minor tick interval.
              i: Inverts tick marks,  so  they  are  drawn  outwards,  rather  than  inwards.   l:  Labels  axis
              logarithmically.   This  only  affects the labels, not the data, and so it is necessary to compute
              the logarithms of data points before passing them to any  of  the  drawing  routines.   m:  Writes
              numeric  labels  at major tick intervals in the unconventional location (above box for X, right of
              box for Y).  n: Writes numeric labels at major tick intervals in the conventional location  (below
              box for X, left of box for Y).  o: Use custom labelling function to generate axis label text.  The
              custom  labelling  function  can  be  defined  with the plslabelfunc(3plplot) command.  s: Enables
              subticks between major ticks, only valid if t is  also  specified.   t:  Draws  major  ticks.   u:
              Exactly  like  "b"  except don't draw edge line.  w: Exactly like "c" except don't draw edge line.
              x: Exactly like "t" (including the side effect of the numerical labels for the major ticks) except
              exclude drawing the major and minor tick marks.

       xtick (PLFLT, input)
              World coordinate interval between major ticks on the  x  axis.  If  it  is  set  to  zero,  PLplot
              automatically generates a suitable tick interval.

       nxsub (PLINT, input)
              Number  of  subintervals between major x axis ticks for minor ticks.  If it is set to zero, PLplot
              automatically generates a suitable minor tick interval.

       yopt (const char *, input)
              Pointer to character string specifying options for vertical axis.   The  string  can  include  any
              combination  of  the letters defined above for xopt, and in addition may contain: v: Write numeric
              labels for vertical axis parallel to the base of the graph, rather than parallel to the axis.

       ytick (PLFLT, input)
              World coordinate interval between major ticks on the  y  axis.  If  it  is  set  to  zero,  PLplot
              automatically generates a suitable tick interval.

       nysub (PLINT, input)
              Number  of  subintervals between major y axis ticks for minor ticks.  If it is set to zero, PLplot
              automatically generates a suitable minor tick interval.
