Hi. The little example was a close approximation to what I want. If it
helps, here's what I REALLY want. I have a data file with sorted
timestamps, one per line, that record the time when something failed. I
want to make a plot of "failures per hour", as a function of time. So I
want to consolidate the data into bins, but instead of "with boxes", I'd
like to plot "with lines". Currently this doesn't work the way I want
because any hour blocks that have 0 failures in them don't get a y=0
point in the line plot.

That's interesting. Unfortunately I'm using feedgnuplot for this, which
cannot currently use tables. It expects a single "plot" command to do
all the work. Suggestions?
