You could replace the CDWordArray with an std::vector<DWORD> (or better
yet, std::vector<__time64_t>).

That would require some controls added to the dialog where the user can
select the granularity. But do you really want that? The graph will look
really ugly if too much is shown.

More complicated than I like things, but if you can make it work, go ahead!

Just don't forget that there are repositories out there with > 50'000
revisions and the stat dialog should not take minutes to show up.
