AHELP for ChIPS 4.0 delete_curve Context: py.chips

Synopsis

Delete the specified curve.

Syntax

delete_curve()
delete_curve( [ChipsId] )
delete_curve( "curve_id" )
delete_curve( "all" )

Description

Depending on the argument, the delete_curve command deletes the current curve, the curve indicated in a ChipsId structure or by the curve_id, or all curves.

  • (no argument) - the current curve is deleted.
  • ChipsId - an optional ChipsId structure containing values to modify the currency state for the command.
  • curve_id - identification tag given to each object that is created; use this to delete a specific curve.
  • all - deletes all curves.

Example 1

chips> add_curve([-23,4,15],[10,8,11])
chips> delete_curve()

Create a curve, then delete it.

Example 2

chips> id = ChipsId()
chips> add_curve([-4,0,4],[0,5,10])
chips>
add_curve(numpy.arange(-4,4),numpy.arange(-4,4)*numpy.arange(-4,4),"id=p
arabola")
chips> id.curve = "crv1"
chips> delete_curve(id)

Two curves are created; the second curve is current after it is created. The id.curve command sets the curve value of the ChipsId structure to the first curve, which has the id "crv1" by default. That curve is then deleted.

Example 3

chips> add_curve([-4,0,4],[0,5,10])
chips>
add_curve(numpy.arange(-4,4),numpy.arange(-4,4)*numpy.arange(-4,4))
chips> delete_curve("all")

Two curves are created, then the delete_curve command deletes them both.

Bugs

See the bugs pages on the ChIPS website for an up-to-date listing of known bugs.
