How to calculate a %age active from event data

[Anonymous]

Hi,

I have a number of machines and data showing a list of events (switch on and off), a small sample of which is shown here:

Machine	Date/Time	Event
01	23/02/2023 10:48:00	Activated
01	23/02/2023 11:23:00	Deactivated
02	23/02/2023 11:52:00	Activated
03	23/02/2023 11:56:00	Activated
01	23/02/2023 12:04:00	Activated
04	23/02/2023 12:34:00	Activated
04	23/02/2023 12:38:00	Deactivated
05	23/02/2023 12:41:00	Activated
03	23/03/2023 12:43:00	Deactivated

Is there any way to show graphically the number (or percentage) of machines "active" over time?

Many thanks

Counting ACTIVE Measure = CALCULATE ( COUNTROWS ( 'Machine Events' ), 'Machine Events'[Event] = "Activated" )

No, not easily, plus a machine may have a number of activate and deactivate events over the time period.

I had considered if it would be possible to have a running count of the number of activate events minus the number of deactivate events, but I'm not sure how to do that.

You may need to get the data into a different shape. Any chance you can pair the Activate and Deactivate records for one machine on one row? Then you can calculate on that row how long the machine was active. Seems that would make it easier to get your final answer.
