panel
A scalar value that determines if the groups of consumer data are to be drawn on the same graph (default=NULL) or on
seperate panels within a single figure. Number of rows and columns of panels can be specified by a 2 element vector. Alternatively,
giving a single value e.g. panel=1 will cause the program to attempt to fit a "reasonable" number of panels to each row and column.
isos
A two element vector containing the reference to each isotope combination for the x and y axis to be rendered in teh figure.
Note, only relevant for datasets contianing >2 isotopes. By default, if there are more than two isotopes, seperate figures will be created for
all possible combinations of isotopes.
leg
A scalar determining how the legend is to be created. Default leg=1 prompts the user to locate the legend on each figure.
leg = 2, puts the legend in a new figure automatically (useful if you want to omit the legend but still want to retain access to the
information). leg = 0 omits the legend entirely.
