The caption says "Articles published by OASPA members und CC-BY"

and the text says  "Data was supplied by the following members of 
OASPA as number of CC-BY articles per year since implementation of 
the license by that publisher:"

Which means, obviously: Regardless of when they became members of 
OASPA. And implicitly, then, the growth of membership cannot influence 
this curve (Should there be a new member next year and they repeat the 
exercise, they would get a completely new curve which would lie 
entirely above the this current one, from the year *that* publisher 
started using CC-BY, not the year the publisher joined OASPA)
