(It comes from this article: https://oeis.org/A254524) The plot is about digitsums of positive integers and how often it has occured upto and including that positive integer. As shown in the example, "35 is the 4th positive integer having digitsum 8 (the others before are 8, 17 and 26) so a(35) = 4." Does that help?
