current_line

Synopsis

Set the specified line as current.

current_line( ChipsId )
current_line( "line_id" )
current_line( "all" )

Description

The current_line command sets the line indicated by the argument as the current line; see "ahelp currency" for general information on currency.

• ChipsId - an optional ChipsId structure containing values to modify the currency state for the command.
• line_id - identification tag given to each object that is created; use this to select a specific line.
• all - sets all lines to be current.

Use the info_current command to retrieve a list of all the current items in the ChIPS session, as shown in Example 1.

Example 1

chips> id = ChipsId()
chips> add_line(.1, .3, .9, .3, "id=flat")
chips> add_line(.3, .8, .8, .2, "id=slope")
chips> id.line = "flat"
chips> current_line(id)
chips> info_current()

Two lines are created; the second line is current after it is created. The id.line command sets the line value of the ChipsId structure to the first line, then the current_line command makes that line current.

The output of info_current for this session is:

Window [win1]
  Frame [frm1]
    Plot [plot1]
      Line [flat]
    Coord Sys [Plot Normalized]

Example 2

chips> add_line(.1, .3, .9, .3, "id=flat")
chips> add_line(.3, .8, .8, .2)
chips> current_line("flat")

Two lines are created. After the second line is created, it is current. The current_line command then sets the first line as the current line.

Example 3

chips> add_line(.1, .3, .9, .3, "id=flat")
chips> add_line(.3, .8, .8, .2, "id=slope")
chips> current_line("all")

Two lines are created. After the second line is created, it is current. The current_line command then makes all lines current.
