Compare data to same time previous day

[ChrisPBIUser]

Need assistance to display in a visual the number of sales made so far today with the same timeframe yesterday.

I have 2 columns, [DateTime] and [Sale] for example a row would be 29/11/2022 10:25:12 and 1.

So what I'm looking to do is compare the sales for today so far against the sales to the same time for for previous day.  I've had a look around and nothing really sticks out to help.

Resolved this now by tweaking your dax, thanks again, @v-yangliu-msft

Hi  @ChrisPBIUser ,

I created some data:

Here are the steps you can follow：

1. Create measure.

Measure =
var _now=now()
var _nowstart =DATE(YEAR(_now),MONTH(_now),DAY(_now))+ TIME(0,0,0)
var _previous=DATE(YEAR(_now),MONTH(_now),DAY(_now)-1)+ TIME(HOUR(_now),MINUTE(_now),SECOND(_now))
var _previoustart =DATE(YEAR(_now),MONTH(_now),DAY(_now)-1)+ TIME(0,0,0)
var _nowsum=
SUMX(FILTER(ALL('Table'),'Table'[Date]>=_nowstart&&'Table'[Date]<=_now),[Amount])
var _previoussum=
SUMX(FILTER(ALL('Table'),'Table'[Date]>=_previoustart&&'Table'[Date]<=_previous),[Amount])
return
IF(
_nowsum > _previoussum ,"The amount today is larger than yesterday","The amount yesterday was larger than today")

2. Result:

That's great, really appreciate your reply, but I missed off one column which is sales agent.  So I have, [SalesAgent], [DateTime],[Sales].  The [Sales] row will always be 1 as an Sales Agent will not be able to create more than one sale at a given moment in time.  I just can't tweak your DAX to include agent
