That one is even stranger.  There are two similar (but not parallel)
lines for imports and another two similar (but again not parallel)
lines for exports.  I can't see if there is anything systematic about
those small differences, and I suspect that there was meant to be
none -- just drawn by someone who didn't have a 45 deg set-square.  

Years ago I inherited some SPlus code which did, in fact, draw a plot
quite similar to that one (but without the inaccuracies).  I remember
it was quite lengthy and complicated, but I don't remember ever having
an inclination to use it for anything since R has so many easier and
better ways of visualizing data.

During the process of changing computer systems several times in the
intervening years, that code was something that went out with the old
faded photos.  Shame that. 

 Excel might have an option to do one like the import-export example.
If it does, it would be a lot easier than using R which has an
altogether different set of values.  If Excel doesn't do that type,
and it's *really* important to have such a plot, I'd be using grid
graphics which is almost infinitely flexible.  Only trouble is, by the
time you'd seen what you can do with grid, you'd likely find that you
no longer felt any urge to make such a plot.
