Yes they do, but it seems a more elegant solution to me to have one 
method to access all the elements of the array. Each element 
represents the frequency of an allele in the gene pool of my 
simulation, if I were to increase the number of alleles I would have 
to write new methods to get these alleles frequencies, as opposed to 
just increasing the number of iterations of a loop. My ultimate aim 
would also be to have an array of strings to generate the EZgraph 
legends, which could be initialised from a text file. This approach 
just seems to me to be closer to achieving good code resuability.

Ah, well then I need to find a workaround (I have one in mind now), 
or just  implement a different method for each allele! Do you think 
it would be useful to extend the functionality of EZGraph to allow 
arguments with a selector in the next Swarm release? Paul Johnson has 
suggested I look at the arborgames example which plots multiple 
integers. I'll have a look and if I think my workaround is better 
I'll post the code to the list.
Thanks for everyone's help on this (as always!)
