current_contour

Context: sl.chips

Syntax

current_contour( ChipsId );
current_contour( "contour_id" );
current_contour( "all" );

Description

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

ChipsId - an optional ChipsId structure containing values to modify the currency state for the command.
contour_id - identification tag given to each object that is created; use this to select a specific contour.
all - sets all contours 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_contour([[1,1,1], [1,3,1], [1,1,1]], 3,3,
[1.1,1.5,2,2.5],"id=levels");
chips> add_contour({1,2,5,3,3,6,0,0,1},3,3);
chips> id.contour = "levels";
chips> current_contour(id);
chips> info_current();

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

The output of info_current for this session is:

Window [win1]
  Frame [frm1]
    Plot [plot1]
        X Axis [ax1]
        Y Axis [ay1]
        Contour [levels]
   Coord Sys [Data]
   Coord Sys ID [plot1_ax1ay1]

Example 2

chips> add_contour([[1,1,1], [1,3,1], [1,1,1]], 3,3,
[1.1,1.5,2,2.5],"id=levels");
chips> add_contour({1,2,5,3,3,6,0,0,1},3,3);
chips> current_contour("levels");

Two contours are created. After the second contour is created, it is current. The current_contour command then sets the first contour as the current contour.

Example 3

chips> add_contour([[1,1,1], [1,3,1], [1,1,1]], 3,3,
[1.1,1.5,2,2.5],"color=lime style=solid");
chips> add_contour({1,2,5,3,3,6,0,0,1},3,3);
chips> current_contour("all");

Two contours are created. After the second contour is created, it is current. The current_contour command then makes all contours current.
