Counter comparison between previous values

‎08-23-2017 09:51 AM

 have a table of data with the structure below. The table is called 'machines'. The absoluteCount column keeps a tally of the count at the time of the dateTime column. I am trying to figure out how to create a new column with the increase in the count between the current absoluteCount value and the previous absoluteCount value by machineID. There are approximately 50 different machines that are tracked in this table. 

 

With the times being down to the minute, I haven't come up with a good way to do this. Any help or directions would be appreciated.

 

Thanks

I figred it out with help from other threads.

 

Created a Rank column to index each machineID by date, otherwise it would index the whole table regardless of machineID:

 

Rank =
VAR machineID = table[machineID]
RETURN
RANKX(
FILTER(
ALL(
table),table[machineID]=machineID), table[dateTime],,ASC)

 

 

Get Previous Day Value using the created Rank:

 

PreviousRowValue =
VAR Index = table[Rank] - 1
Return
CALCULATE(
MAX(table[absoluteCount]),
FILTER(ALLEXCEPT(table,table[machineID]),table[Rank] = Index))
