set arrow
=========

   Arbitrary arrows can be placed on a plot using the `set arrow' command.

   Syntax:

             set arrow {<tag>} {from <sx>,<sy>{,<sz>}}
                               {to <ex>,<ey>{,<ez>}} {{no}head}
             set noarrow {<tag>}
             show arrow

   Unspecified coordinates default to 0. The x, y, and z values are in the
graph's coordinate system. The z coordinate is only used in `splot' commands.
<tag> is an integer that identifies the arrow. If no tag is given, the lowest
unused tag value is assigned automatically.  The tag can be used to delete or
change a specific arrow. To change any attribute of an existing arrow, use the
`set arrow' command with the appropriate tag, and specify the parts of the
arrow to be changed. Specifying nohead requests the arrow be drawn without a
head (yielding a line segment). By default, arrows have heads.

   Arrows outside the plotted boundaries are permitted but may cause device
errors.

   Examples:

   To set an arrow pointing from the origin to (1,2), use:
             set arrow to 1,2
   To set an arrow from (-10,4,2) to (-5,5,3), and tag the arrow number 3, use:
             set arrow 3 from -10,4,2 to -5,5,3
   To change the preceding arrow begin at 1,1,1, without an arrow head, use:
             set arrow 3 from 1,1,1 nohead
   To delete arrow number 2 use:
             set noarrow 2
   To delete all arrows use:
             set noarrow
   To show all arrows (in tag order) use:
             show arrow
