function XfigureGraph(y, color, x)
% XfigureGraph - adds xy line graph data to the xFigureObject cell array
% in the workspace
% line graphs will be displayed in an inset in the MatlabViewer app
% 
% Syntax:  
%     XfigureGraph(y)
%     XfigureGraph(y, color)
%     XfigureGraph(y, color, x)
% 
% Inputs:
%    y - Nx1 or NxM array of y values for the line graph(s)
%        if M == 1 a single line graph will be specified
%        if M >  1 the line to be displayed can be selected using a
%           slider in the 
%        if M >  1 M should be equal to M in XfigurePatch Vertexcolors
%    color - 1x3 RGB array, 
%        if not specified color will default to [0, 0, 0] (black line)
%    x - Nx1 array of values,
%        if not specified will default to all x steps being equal
