I know we can make histograms conditional based
on other inputs. But suppose I wanted to be very
arbitrary about what I allowed into the histogram
and didn't have a good clear / reliable logic. For
example, I would like to do series of acceleration
pulls at varying throttle positions to fill up the map
but want to exclude all the closing throttle, opening
throttle, decel, transitional "stuff" of all kinds and
only work from the "meat" of the pulls.

I am thinking it would be sweet to be able to select
multiple regions of the time-axis for inclusion / exclusion.
