"some time" is only two hours for the monthly, and a day for the yearly.

Odds are that the monthly is done by now.  You can just delete the broken
*month.png files and *year.png files if you don't want them visible, they
will be recreated automagically.

Isn't this is what you just asked for?!?!

OK, maybe you want this:

Edit the .log files and delete everything below the timestamp of the
first known-good data.  The graphs will now show zero values for anything
earlier in time, where you've removed the data.  MRTG will fill the logs
with zeroes next time it runs.  You'll need to convert calendar date/time
to epoch-seconds in order to figure out where to snip, of course.

The historical data will be lost where you edited it, but I assume that's
what you want.
