Having some hundreds of builds each of which is associated with various performance measurements, the plots of the performance values show different date strings in the labels for same builds.

E.g., build #129 took place on Jul 28 (see attached right date string plot), but for some reason it is written down as Sep 4 in one of the plots (see attached bad date string plot).

The version 1.4 of Plot Plugin had other issues (index out of bounds and some SimpleDateFormatter issues reported elsewhere).
