How to measure the decrease or increase by newest date

[mehlenbae2]

I am trying to measure the total increase or decrease of virus count by month by Configuration Item but I am unable to do this because the Virus Count is in one column and I have hundreds of thousands configuration items. I am hoping to put this in a line chart on PBI.. How can I do this easily? I am not that great with DAX.. Virus counts can increase and decrease anytime and I want to do see it all in one large line chart. Is this possible?

Here is my dataset:

Hi @mehlenbae2 ,

Here I create a sample to have a test.

Tables:

Calendar = ADDCOLUMNS(CALENDARAUTO(),"Year",YEAR([Date]),"Month",MONTH([Date]))

Relationship:

Measure:

Difference = 
VAR _CURRENT = CALCULATE(SUM('Table'[Virus Count]))
VAR _PREVIOUS = CALCULATE(SUM('Table'[Virus Count]),PREVIOUSMONTH('Calendar'[Date]))
RETURN
_CURRENT - _PREVIOUS

Result is as below.

@mehlenbae2 , the expected output is not clear. Can you share sample data and sample output in table format? Or a sample pbix after removing sensitive data.

I think these can help
