11.43 point

point [ item <id> ] [at] <vector> [ label <string> ]
                    [ with { <option> } ]

The point command allows a single point to be plotted on the current multiplot canvas independently of any graph. It is equivalent to plotting a data file containing a single datum and with invisible axes. If an optional label is specified then the text string provided is rendered next to the point. The with modifier allows the style of the point to be specified using similar options to those accepted by the plot command.

All vector graphics objects placed on multiplot canvases receive unique identification numbers which count sequentially from one, and which may be listed using the list command. By reference to these numbers, they can be deleted and subsequently restored with the delete and undelete commands respectively.
