I'm very familiar with PCA. There are so, so many ways you can apply it to this problem.
Assuming the simplest interpretation of what the analysis did, then it's saying "the variance of the biggest variance direction stays constant". Which in itself is an interesting thread to tug on, but the charts aren't how you'd present such a result.
