I don't have any idea for a workaround, other than detecting the case where the sample contains a single observation and therefore abandoning the notion of producing a plot.

However, in current git there's now code to ensure that we don't pass an empty xrange (such as [1980:1980]) to gnuplot, even when there's just a single observation available. I suppose this could be OK for personal usage but I wouldn't really want to see a function package that was willing to "plot" a single observation.
