current_label

Context: sl.chips

Syntax

current_label( ChipsId );
current_label( "label_id" );
current_label( "all" );

Description

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

ChipsId - an optional ChipsId structure containing values to modify the currency state for the command.
label_id - identification tag given to each object that is created; use this to select a specific label.
all - sets all labels 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_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);
chips> info_current();

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:

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.
