trimming down the log file for a report?

I have a couple polygraph runs in which the polyclt continued to run long
after the polysrv (and the test itself) ended, and it was over the weekend,
so I hadn't actually stopped the client until it had been running for 100
hours. The problem with this is that the generated graphs all have the
scale of 100 hours for them, and so the important 14 hours of the test are
all bunched up at the beginning, and the graph isn't as easy to look at. My
question is: is it possible to trim out data from the log file itself
(which isn't very reader friendly) or can I tell the report to do that? I
already use the --log_extractor_opts "--phases top2" to see only the top2
info for most of the report, but the graphs show the whole test. I'd love
to be able to do a report only, say, the first 15 hours of the test. Is
this possible?
