Counting net value

[#1]

Below is a data of three companys (ID), which all have random number of transactions (rows).

Now I would like to have a net value for each company - if one or more rows for that company equals 1, the net value for that company would be 1. If all the rows for the company are 0, the net value would be 0.

ID    Data

1     1

1     0

1     1

1     0

2     0

2     0

2     0

3     0

3     1

3     1

Int this case the net values for companies would be

ID     Net value

1     1

2     0

3     1

How can I count that net value? There must be a simple solution, just can't figure it out...

[giakoum · Accepted solution]

Use if(sum(trans)=0,0,1) as an expression in a chart ( straight table should work fine).

Group by ID and don't forget to uncheck "Suppress Zero-Values"...

no need to keep sum also you can use below

If(Data=0,0,1)and uncheck Supress zero values in Presentation of chart properties

Thanks - both of you. I was thinking this from the wrong end, I guess.
