5.1 arrow

arrow [from] <x>, <y> [to] <x>, <y> [with <option> ... ]

Arrows may be placed on multiplot pages independently of any plots using the arrow command, which has syntax:

arrow from x,y to x,y

The arrow command may be followed by the ‘with’ keyword to specify to style of the arrow. The style keywords which are accepted are ‘nohead’, ‘head’ (default) or ‘twohead’, in addition to keywords such as ‘colour’, ‘linewidth’ or ‘linetype’, which have the same syntax and meaning as they do in the plot command. An example would be:

arrow from x,y to x,y with twohead linetype 2 colour blue

Arrows receive unique identification numbers which count sequentially from one, and which are output to the terminal after the arrow command is called. By reference to these numbers, they can later be deleted and undeleted with the delete and undelete commands respectively. For example:

delete 2
