Month over Month

[Johnny-Mclawdog]

Hello I am trying to show a month by month comparison betweeen total views. I have been looking at youtube and this channel as well for answers and im not sure if I dont have enough data or what exactly I am doing wrong. I only have 3 months worth of data so maybe thats my issue 

I started out with just one dataset "data" which has a column of "Total Views"

My first attempt i did:

tv = SUM(data[Total Views])

total views last month =

CALCULATE(

[tv],

PARALLELPERIOD(

'data'[Date].[Date],

-1,

MONTH)

)

but i just get the exact same number for that month when trying to graph it ot show it in a table

also tried this code:

total by month LM = CALCULATE(SUM(data[Total Views]),DATEADD(data[Date].[Date],-1,MONTH))

but gives me the same results 

also tried 

PrevMonthRev = CALCULATE(sum(data[Total Views]),PREVIOUSMONTH('data'[Date].[Date]))

but thats not even giving me any numbers 

tried 

last month = CALCULATE(SUM(data[Total Views]),DATEADD(data[Date].[Date],-1,MONTH),ALL(data[Date]))

and thats giving me the same numbers as well 

The end goal would be to have a bar chart that would show the difference between the current month and past month

@Johnny-Mclawdog Hi Johnny, when I faced the same issue (where the current month value and previous month value are the same) under such a simple time function, there was issue with either date table or date column. I recommend to double check them. or please share sample data.
