xlim command changes the axis limit of the figure.

How can i also limit data that is contained by the figure?

Appearently, even though xlim is applied data is still there.

cleanfigure.m file from matlab2tikz can take care of this issue.

If when you say limit data, you mean restrict the range of data values, then use ylim

   x = randn(100,1);
   plot(x);
   set(gca,'xlim',[1 25],'ylim',[-1 1])

no data range is not what i am asking.

let's say i have a data set of 5000 elements. but only 1500 elements are shown in the figure. still when i save this figure, it will still contain data that is not shown in the figure.
