Scaling to 100% : two dimensions / one expression

[#1]

Hello all,

It sounds easy, however I am not able to find the right solution.

I have go a table who looks like this (simplification):

Time             Recognition

7                       YES
7                       YES
7                       YES

7                       NO

8                       NO

8                       NO

TIME and RECOGNITION are the dimension and ANSWER is the expression =count(Recognition).

What I want to see is the distribution indexed to 100% for EACH moment in TIME (7 and 8).

If I thickbox RELATIVE and adjust the Axe maximum to 1 I get what I show here beneath.

===> 

However, That is not what i need. The total for EACH moment in time needs to be 100%, not the combination of the two moments in TIME.

I have been thinking about this all day by now. It drives me crazy.

If you can help me with this, you are my hero.

Kinds regards,

Tim

I found it myself after a good and strong coffee.

Today my hero is me.

=count(Recognition ) / count(TOTAL <Time> Recognition)
