Well in this case you might be stuck with local variables unless you wanted to use something like a queue to store the plots. When you create a local variable of the graph, it should be an array. Now what you have to do is read the local variable, replace an element with a new cluster representing the plot, and output this array to another local variable of the graph. You're essentially doing the same thing as the shift register idea I described, but with local variables.
This is what I'm talking about:
