I hope I can describe this well enough so that someone might be able to help me.
I'm looking for a general equation that includes, for example, the following coordinates:
I've figured out two ways to describe what I want. Either x = the sum of all y's less than or equal to it, or x = y plus the x immediately preceding it in the series.
I'd be most interested in whether this could be graphed as a curve.
Thanks in advance, and I hope this is clear.
