Calculated year dimension

[#1]

Hello everyone,

I want to have a year over year comparison in a bar chart. So my idea is this:

Bar 1:

current date to the same date last year (so for example 18.09.2014 - 18.09.2013)

Bar 2:

date last year to the same date 2 years ago (so for example 18.09.2013 - 18.09.2012)

etc.

Do you know what I mean?

Any idea how to realise this?

I guess that I have to use a calculated dimension...

Thanks!

Best regards,

Moritz

Dimension:

=GetFieldSelections(Date)

Expressions:

Bar1: sum({<Date={"<=$(=Max(Date(Date))) >$(=Max(AddYears(Date,-1))) "}>}Volume)

Bar2: sum({<Date={"<=$(=Max(AddYears(Date,-1))) >$(=Max(AddYears(Date,-2))) "}>}Volume)

Did it now with a Value list:

In the dimension it looks like this:

=ValueList(v1, v2, v3, v4, v5)

v1 is Today      -      Today-1Year

v2 is Today-1Year      -     Today-2Year

v3 is Today-1Year      -     Today-3Year

v4 is earlier than Today -3Year

v5 is Total

In the expression like this:

=pick(match(

            ValueList(v1, v2, v3, v4, v5)

        , v1, v2, v3, v4, v5)

    ,sum({<DateField= {">=18.09.2013 <=18.09.2014"}>} ValueField)

    ,sum({<DateField= {">=18.09.2012 <=18.09.2013"}>} ValueField)

    ,sum({<DateField= {">=18.09.2011 <=18.09.2012"}>} ValueField)

    ,sum({<DateField= {"<=18.09.2011"}>} ValueField)

    ,sum(ValueField)

)

May help someone else
