Graphs dates are completely out of order and I can't figure out why

[photex]

I've tried rebuilding indexes over and over, but the graphs that show
events by day our out of order and it isn't awesome.
Has anyone else had this problem? I'm running this on a RHEL 4.4 box,
could it be a php or gd version issue?

Thanks

This may have been caused by your event data being overwritten with
new events if your system failed to return the correct event tracking
#'s, thus when indexing takes place the dates appear out of order.

Unfortunately a repair of this is not possible as the original
(Aanval) records have been corrupted. The latest builds of Aanval
includes several checks and measures to protect against this from
happening.
