    how to limit the range of values to sum in a graph



      I have this kind of problem:


      I have a list of values from 1 to n, i would like to sum or to do a media in a graph not for all values but for a limited range of them,

      for example 1+(5% of 1)....and n-(5% of n),

      which kind of expression i should use ?
