AHELP for CIAO 3.4 ln Context: chips

Synopsis

Defines the current line.

Syntax

chips> [D #] LN {# [,#, ...] | #:# | ALL}

where # is an integer argument and #:# specifies an inclusive range of
line numbers.

Description

See the D command for more information about this argument.

Note that if a non-existent line is specified, ChIPS will act on the current line.

Example 1

chips> CURVE data/example.dat X 1 Y 2
chips> LINE 2.0 1.0 2.0 4.0
chips> LINE 1.25 5.0 1.8 5.0
chips> LINE DASH

A curve is plotted and two lines are placed on the plot. The first line is designated line number 1 and the second is line number 2; Line 2 is also the current line, since it is the most recently created line. The command LINE DASH acts on the current line, changing it to a dashed line.

Example 2

chips> D 1 LN 1
chips> LINE DASH

The command D 1 LN 1 defines line number 1 as the current line, then the LINE DASH command changes it to a dashed line.

Example 3

chips> LN 2
chips> LINE WIDTH 4.0

Line 2 is defined as the current line. The LINE WIDTH 4.0 command acts on the line, changing it to a width of 4.0.

Bugs

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