Help with a bar/lines graphic

[#1]

Hello everyone!

Please, we need some help, we are trying to estimate the cumulative sum of sales in the last 12-month build-up but we do not work well. We have 2 fields Date and Ingresos (Sales). Our code is:

=if("Year([Date])"=2008,

if("Month([Date])"='jan' , sum({$<"Year([Date])"={2007}, "Month([Date])"={"feb","mar","apr","may","jun","jul","aug","sep","oct","nov","dec"} >} total [Ingresos]) + sum ({$<"Year([Date])"={2008}, "Month([Date])"={"jan"} >} total [Ingresos]),(

if("Month([Date])"='feb' , sum({$<"Year([Date])"={2007}, "Month([Date])"={"mar","apr","may","jun","jul","aug","sep","oct","nov","dec"} >} total [Ingresos]) + sum ({$<"Year([Date])"={2008}, "Month([Date])"={"jan","feb"} >} total [Ingresos]),(

if("Month([Date])"='mar' , sum({$<"Year([Date])"={2007}, "Month([Date])"={"apr","may","jun","jul","aug","sep","oct","nov","dec"} >} total [Ingresos]) + sum ({$<"Year([Date])"={2008}, "Month([Date])"={"jan","feb","mar"} >} total [Ingresos]),(

if("Month([Date])"='apr' , sum ({$<"Year([Date])"={2007}, "Month([Date])"={"may","jun","jul","aug","sep","oct","nov","dec"} >} total [Ingresos]) + sum({$<"Year([Date])"={2008}, "Month([Date])"={"jan","feb","mar","apr"} >} total [Ingresos]),(

if("Month([Date])"='may' , sum({$<"Year([Date])"={2007}, "Month([Date])"={"jun","jul","aug","sep","oct","nov","dec"} >} total [Ingresos]) + sum ({$<"Year([Date])"={2008}, "Month([Date])"={"jan","feb","mar","apr","may"} >} total [Ingresos]),(

if("Month([Date])"='jun' , sum({$<"Year([Date])"={2007}, "Month([Date])"={"jul","aug","sep","oct","nov","dec"} >} total [Ingresos]) + sum ({$<"Year([Date])"={2008}, "Month([Date])"={"jan","feb","mar","apr","may","jun"} >} total [Ingresos]),(

if("Month([Date])"='jul' , sum({$<"Year([Date])"={2007}, "Month([Date])"={"aug","sep","oct","nov","dec"} >} total [Ingresos]) + sum ({$<"Year([Date])"={2008}, "Month([Date])"={"jan","feb","mar","apr","may","jun","jul"} >} total [Ingresos]),(

if("Month([Date])"='aug' , sum({$<"Year([Date])"={2007}, "Month([Date])"={"sep","oct","nov","dec"} >} total [Ingresos]) + sum ({$<"Year([Date])"={2008}, "Month([Date])"={"jan","feb","mar","apr","may","jun","jul","aug"} >} total [Ingresos]),(

if("Month([Date])"='sep' , sum({$<"Year([Date])"={2007}, "Month([Date])"={"oct","nov","dec"} >} total [Ingresos]) + sum ({$<"Year([Date])"={2008}, "Month([Date])"={"jan","feb","mar","apr","may","jun","jul","aug","sep"} >} total [Ingresos]),(

if("Month([Date])"='oct' , sum({$<"Year([Date])"={2007}, "Month([Date])"={"nov","dec"} >} total [Ingresos]) + sum ({$<"Year([Date])"={2008}, "Month([Date])"={"jan","feb","mar","apr","may","jun","jul","aug","sep","oct"} >} total [Ingresos]),(

if("Month([Date])"='nov' , sum({$<"Year([Date])"={2007}, "Month([Date])"={"dec"} >} total [Ingresos]) + sum ({$<"Year([Date])"={2008}, "Month([Date])"={"jan","feb","mar","apr","may","jun","jul","aug","sep","oct","nov"} >} total [Ingresos]),(

if("Month([Date])"='dec' ,sum ({$<"Year([Date])"={2008}, "Month([Date])"={"jan","feb","mar","apr","may","jun","jul","aug","sep","oct","nov","dec"} >} total [Ingresos])))))))))))))))))))))))))

Hi

This link should provide you with some ideas: http://community.qlik.com/forums/t/29231.aspx

Also, as Oleg says in the above link, there are many other examples in this forum discussing 12 month rolling values, just do a search for 12 month rolling and take a look.
