current_label

Context: labels

Synopsis

Set the specified label as current.

Syntax

current_label(id)

Description

The function arguments.

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

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

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

Examples

Example 1

chips> id = ChipsId()
chips> add_label(.35,.9,"The top of the frame.", "id=top")
chips> add_label(.35,.1,"The bottom of the frame.","id=bot")
chips> id.label = "top"
chips> current_label(id)

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

The output of info_current for this session is:

chips> print(info_current())
Window [win1]
  Frame [frm1]
    Plot [plot1]
      Label [top]
    Coord Sys [Plot Normalized]

Example 2

chips> add_label(.35,.9,"The top of the frame.", "id=top")
chips> add_label(.35,.1,"The bottom of the frame.","id=bot")
chips> current_label("top")

Two labels are created. After the second label is created, it is current. The current_label command then sets the first label as the current label.

Example 3

chips> add_label(.4,.5,"area={\\pi}r^2")
chips> add_label(.35,.9,"The top of the frame.")
chips> current_label("all")

Two labels are created. After the second label is created, it is current. The current_label command then makes all labels current.
