The setting of "set samples" has no effect on this plot, because the
plot is made from data:

	plot  datafile u (($1)/365.25+1945):(f3($1)) w l

But neither the current CVS version nor 4.6.2 shows the problem here.
The reason for that may very well be that the subset of the data
presented to us is missing one data point (at 22671, transformed x value
2007.07), which might be just where that "peak" is.
