JFIG is the jGraph module of jLab.

 JFIG  Shorthand for tweaking figures. 
    JFIG is a shorthand syntax for tweaking figures.  It works like this.
       jfig equal ticksout yrev axis|[5 45 5 45] caxis|[-8 8] ...
            title|['Demonstration of JFIG'] colorbar|['eastoutside']
    This call to JFIG is equivalent to
       axis equal, set(gca,'tickdir','out'), set(gca,'ydir','reverse')
       axis([5 45 5 45]), caxis([-8 8]), title('Demonstration of JFIG')
    JFIG takes two kinds of arguments.  The first are one-word commands, 
    such as 'equal', 'ticksout', and 'yrev'.  A list is provided below.  
    The second kind of argument is a function with one input argument.  The
    function name is separated from the argument by a vertical bar, '|'.
    For these the function is simply called with the following argument.  
    Note strings or arrays have to be enclosed in brackets in this format.
    Arguments can also be variables, i.e., the following also works:
        ax=[5 45 5 45]; cax=[-8 8];  jfig axis|ax caxis|cax
    Any single-argument function can be called in this way.   
    There are two exceptions for the single-argument functions.  Firstly, 
    colorbar is called with GCA as its first argument whatever appears
    after the '|' as its second argument.  Secondly, if the function name
    is 'eval', its argument will be evaluated in the caller.  
    The one-word commands and the single-argument functions can appear in
    any order within a call to JFIG.
    By default, JFIG turns on hold and also turns on the axis box.

    'jfig --f' generates a sample figure using the code presented above.
    Usage: jfig equal ticksout yrev axis|[5 45 5 45] caxis|[-8 8]
