LINERING is the jGraph module of jLab.

 LINERING  Moves lines through the current line style order.  
 
    LINERING works like a moveable highlighter, picking out a group of
    lines from the current plot.  This is accomplished by moving the
    line handles by a specified amount with respect to the current
    line style, color, and width order.
 
    Different subplots in the current figure may be locked together,
    highlighting comparable groups of lines.
 	
    LINERING(N), where N is a *real* integer, moves all line handles
    in the current axes N steps forward (or backward for N<0) with
    respect to the current style order.  When N is an *imaginary*
    integer, LINERING moves the imag(N)th line to the first position
    with respect to the current style order.
 
    LINERING N also works, where N is an number (not a variable whose
    value is a number).
 
    LINERING with no arguments is the same as LINERING(1), and returns
    the lines to their original styles.
    
    LINERING LOCK and LINERING UNLOCK lock and unlock all axes in the
    current figure.  When LOCK is on, calls to LINERING or LINESTYLE
    are applied to all lines in the current figure.
