current_point

Context: sl.chips

Syntax

current_point( ChipsId );
current_point( "point_id" );
current_point( "all" );

Description

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

ChipsId - an optional ChipsId structure containing values to modify the currency state for the command.
point_id - identification tag given to each object that is created; use this to select a specific point.
all - sets all points 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_point(.4, .5, "id=sq style=square");
chips> add_point(.8, .2, "id=tri style=uptriangle size=12");
chips> add_point(.6, .5, "style=plus");
chips> id.point = "sq";
chips> current_point(id);
chips> info_current();

Three points are created; the second point is current after it is created. The id.point command sets the point value of the ChipsId structure to the first point, then the current_point command makes that point current.

The output of info_current for this session is:

Window [win1]
  Frame [frm1]
    Plot [plot1]
      Point [sq]
    Coord Sys [Plot Normalized]

Example 2

chips> add_point(.4, .5, "id=sq style=square");
chips> add_point(.8, .2, "id=tri style=uptriangle size=12");
chips> add_point(.6, .5, "style=plus");
chips> current_point("sq");

Three points are created. After the second point is created, it is current. The current_point command then sets the first point as the current point.

Example 3

chips> add_point(.4, .5, "id=sq style=square");
chips> add_point(.6, .5, "style=plus");
chips> current_point("all");

Two points are created. After the second point is created, it is current. The current_point command then makes all points current.
