AHELP for CIAO 4.6 ChIPS v1

delete_point

Context: points

Synopsis

Delete the specified point.

Syntax

delete_point()
delete_point(id)

Description

The function arguments.

Argument Description
id A ChipsId structure identifying the item, or a string containing the name of the object.

If no argument is given then the current point is deleted, otherwise the argument determines what to delete.

Example 1

chips> add_point(.6, .5, "style=plus")
chips> delete_point()

Create a point, then delete it.

Example 2

chips> id = ChipsId()
chips> add_point(.4, .5, "id=sq style=square")
chips> add_point(.8, .2, "id=tri style=uptriangle size=12")
chips> add_point(.6, .5, "style=plus")
chips> id.point = "sq"
chips> delete_point(id)

Three points are created; the second point is current after it is created. The id.point command sets the point value of the ChipsId structure to the first point. That point is then deleted.

Example 3

chips> add_point(.4, .5, "id=sq style=square")
chips> add_point(.8, .2, "id=tri style=uptriangle size=12")
chips> delete_point("all")

Two points are created, then the delete_point command deletes them both.
