Dear FileMakers

 

I have two data loggers, each outputting data to a CSV file, which then gets imported into two separate tables on my FM DB.

 

One data logger creates a record each second, the other each minutes.

 

So I can splice the seconds data together with the minutes data, I am trying to create a third table with time in minutes, which averages the data from the seconds table.

 

So I'm trying to create a third table to average the output of the seconds table into minutes. 

 

Starting at the Average table, I need to get the value in the time field (say 12:20) and to then go to the Seconds table, and find all records between 12:20:00 and 12:20:59, take an average of the specific field and then paste that back into the relevant field within the Average table.

 

That's how the code would run in my head - but I might be way off base.

I hope someone can unpick this for me and help.

 

Many thanks,

 

Ben 

I don't think you need a third table here.

 

 

Define a calculation field cMinute in the Seconds table (result is Time) =

Timefield - Seconds ( Timefield )

and use it to establish a relationship between the two tables matching cMinute to the timefield in in the other table. Then use a calculation field in the Minutes table =

Average ( Seconds::Valuefield )

to average the values of the related records in the Seconds table.

 

 

 

Note:

Seconds() is a Filemaker function; although naming a table "Seconds" is valid, it could lead to confusion.

Thank you Comment, that is a very elegant solution and works perfectly.
