hist [-option(s)] [vector(s)]; build a histogram

Output is a GPS that describes a histogram display.  Input
is a vector of odd rank, with odd elements being bucket
limits and even elements being bucket counts (see bucket).
If no vector is given, the standard input is assumed.

Options:

     a         Suppress axes.
     b         Plot histogram with bold weight lines,
               otherwise use medium.
     f         Do not build a frame around plot area.
     g         Suppress background grid.
     rn        Put the histogram in GPS region n, where n is
               between 1 and 25 inclusive.
     xn (yn)   Position the histogram in the GPS universe
               with x-origin (y-origin) at n.
     xa (ya)   Do not label x-axis (y-axis).
     yln       n is the y-axis low tick value.
     yhn       n is the y-axis high tick value.

Example:   hist -r5,ya A
outputs the histogram described by vector A and locates it
in region 5 of the GPS universe, with no y-axis labels.
