Show previous 6 months, dynamic

[sfong002]

Hello,

New to Power BI, so I wanted to know if there is a way to dynamically create a line chart showing the past 6 months of my data.

In my data I have a "month_year" column, and to retrieve the current month everytime, so that I don't have to filter into the new date, I created a measure 

Max Month = CALCULATE(max(Table1[month_year]), all(Table1)) and then created a new column

Latest = if(Table1[month_year]=[Max Month],"Curent Month","")

Now I can show the last 6 months easily by creating a hierarchy with month_year and filtering in the 6 month dates, but is there a formula I can use to dynamically display the last 6 months

data is suppose to just show the revenue growth for 6 months

Hi @sfong002,

In your scenario, you can create a calculated column using the following formula, then use the column in slicer. For more details, you can check the screenshots below.

Date Periods = 
VAR Datediff =
1
* ( Table1[Date] - TODAY () )
RETURN
SWITCH (
TRUE,
AND ( Datediff <= 0,Datediff >= -180 ), "Last 6 Months",
Datediff < 180, "Older than 6 Months"
)

Thanks,

If you only need the last 6 months' data anywhere in your report, you can filter the data when you get it, via

• Edit Query,
• Click the filter drop-down on your date column, 
• Click Date Filters > In the Previous...

If you need that filter applied to just one visual in your report, you may need some more dynamic filtering such as that described by Chris Webb at Building Relative Date Reports in PowerPivot
