Frequency vs. temp

No, that's a plot of temp vs time and another plot from a different file of 
drift vs time.  If you can capture both at the same time then you can ignore 
the time in the file and plot drift vs temp.

You can probably do it with some post processing to merge 2 files.  For me, 
it was easier to fix the data collection side.

The "every hour or so" is pretty ugly.

Better to get it from loopstats.  Or from the kernel.  I'll send you python 
code if you want it.
