running good/playing bad?

What your graph is telling you is that although you are 4 buyins down, it's only luck that stopped you being 8 buyins down. But it's also a shit measure of luck, as to be 8 buyins down in 1k hands means you are either really, really shit at poker, or you've been real unlucky in some of the many other aspects of luck that your AIEV line does not measure, ie you havd had KK run into AA a few times, or been beaten set over set or w/e.

just focus on making solid decisions at the tables and results will take care of themselves.

There's nothing to be inferred here I don't think, especially since its such a small sample.
