Aggregation Function

[#1]

Hi All,

I had some an issue while using an aggregation function. There are 3 fieds in my table : marks,subject and teacher.

I am trying to make a bar chart where i can find the sum of average marks (average marks for each subject) for each teacher.The attached the qvw would illustrate my problem.

I used the expression sum(aggr(avg(Marks),Subject))  and Teacher as the dimension. However, I am getting erroneous results. Is there some way I can fix the problem ?

Thanks,

Neeraj

I think you'll want to aggregate over the Teacher field as well:

=sum(aggr(avg(Marks),Subject, Teacher))
