Hi Ulrich, The date is in AbsoluteTime format. You can convert it using DateList like this: dl = {DatePlus[#], RandomInteger[{1, 40}]} & /@ (Range[12]*-1); Manipulate[ { DateListPlot[dl, Joined -> True], Dynamic[{DateList[p1[[1, 1]]], p1[[1, 2]]}] } // Column, {{p1, dl[[4]]}, Locator} ] Cheers -- Sjoerd On Oct 1, 1:33 pm, Ulrich Arndt <ulrich.ar... at data2knowledge.de> wrote: > Hi all, > > I am working with mathematica 7 - just started... > Is it possible to use Locator with DateListPlot? > > dl = {DatePlus[#], RandomInteger[{1, 40}]} & /@ (Range[12] * -1) > Manipulate[ > DateListPlot[dl, Joined -> True], > Dynamic[p1], > {{p1, dl[[4]]}, Locator}] > > is at least not doing what I expected. > The varibale p1 is set correctly but not placed correctly and if you > move the locator p1[[1]] is changed from a date to a real... > > Kind regards Ulrich
