No, because there are no missing values in that dataset.  gnuplot cannot 
know the difference between a data point just not existing and one being 
omitted on purpose.  If you want such a difference to be made, you have 
to tell gnuplot about it explicitly --- by putting missing points into 
the file, marked appropriately.  Or put blank lines in there.  Those 
will also break 'with lines'.

If it's hard even for you, how do you expect gnuplot to manage it?
