SynopsisSet the specified label as current. Syntaxcurrent_label( ChipsId ) current_label( "label_id" ) current_label( "all" ) DescriptionThe current_label command sets the label indicated by the argument as the current label; see "ahelp py.chips 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 in Example 1. Example 1chips> 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> print(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]
Label [top]
Coord Sys [Frame 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. BugsSee the bugs pages on the ChIPS website for an up-to-date listing of known bugs. See Also
