graphic with lines with field "year" on dimension and expression

[#1]

Hello,
i'm new user of qlik.

I have already one problem with qlik.

i'm loading a table with these columns: years (example: 2012, 2013, 2014), products (example: a,b,c), import € (1, 2, 3)

i want create a graphic with lines. this graphic have to illustrate the dimension "years" in axis x and the % change of € between every years with last year in y axis (example: € 2014 - € 2012 in year 2014, € 2013 - € 2012 in year 2013).

i'm thinking to replicate the "€" column in the load script but i hope to find another solution with your help.

How i can do?

thanks
