Aggr/Set Issue

Fri, 17 Feb 2012 17:37:17 GMT

Hello Everyone,

I am having an issue with aggregation in a chart (or at least that's what I think the problem is). I have simplified the dataset to the following - each line representing a production "load".

StartTime	Part
1:00	A
1:00	B
1:00	C
1:30	A
2:00	D
2:30	B
3:00	B

The problem is with the first three lines, which form 1 "combined load". How can I make a chart using Part as the dimension that will sum up the "loads", but taking into consideration that the first 3 lines only represent 0.33... of a load. i.e. the graph would show A=1.3333, B=2.3333, C=0.33333 and D=1.

I have tried various forms of set analysis and aggregration, but nothing I've come up with fits the bill. What I've been trying to do is - for each line, 1/Total Lines with the same start time. I just don't know what/if any language there is for that.

Any help is greatly appreciated.

Try this

Create a straight table with dimension Part and as expression
=sum(aggr(nodistinct 1.0/count(distinct Part),StartTime))
