FONTSIZE is the jGraph module of jLab.

 FONTSIZE Rapidly set title, axes, label, and text fontsizes.
 
    FONTSIZE(TITLES, LABEL, AXES, TEXT) sets the fontsizes of all titles, 
    x/y/z labels, axes, and text objects in the current figure to the 
    specified values.  To avoid changing a fontsize, use the empty set, as 
    in FONTSIZE(14,[],12).
 	
    FONTSIZE('NAME'), where NAME refers to a  predetermined set of font 
    sizes, also works.  Type FONTSIZE with no arguments to see a list of 
    available fontsize sets. 
 
    When the input arguments are numbers (not named variables) or a string 
    referring to a fontsize set, parenthesis may be omitted.  For instance: 
   
 	    FONTSIZE 14 12 12 10
 	    FONTSIZE DEFAULT   
 
    Additional named fontsize sets may be created by the user, as described
    in JLAB_SETTINGS.
