Hi folks. This should be really easy, but it is eluding me. Consider the following points and graphic. x=List[DateString[DatePlus[#],{"Day","MonthNameShort","YearShort"}],#]&/@Range[10]; y=ReplacePart[Take[x,{2,-1,2}],{_,-1}->10]; DateListPlot[{x,y},PlotRange->{0,12}] The plot consists of one diagonal and one horizontal set of points. My problem is that, in the graphic, I would like to join pairs: y[[1]] and y[[2]]; y[[3]] and y[[4]]. An obvious (if ugly) hack is as follows: z=Partition[y,2]; DateListPlot[{x, z[[1]], z[[2]]}, Joined -> Join[{False}, Table[True, {Length[z]}]], PlotRange -> {0, 12}] Unfortunately, in the real version of this problem, the length of y is variable, so I need a solution in terms of y, which does not involve manually entering parts of z. And that is where I get stuck. Any suggestions? Many thanks indeed. Luke
