Show 30 days data in visual before the date selected in date slicer

[Vaishali04]

Hi All,

I have a date slicer and a line chart. My requirement is on selecting a date in date slicer , 30 days of data should be displayed in line chart ahead of date selected in date slicer.

If someone came across same scenario. Please suggest the solution.

Regards

@Vaishali04 , You can get the last 30 days like the example with help from the date table 

Rolling 30 = CALCULATE(sum(Sales[Sales Amount]),DATESINPERIOD('Date'[Date],max('Date'[Date],-12,DAY)))

But this will not give trend for last 30 Days. Follow the approach in the video

@amitchandak  Thanks for the logic 

The logic is working fine but still the chart is showing data only for the date selected in the slicer and not of past 12 or 30 days.

Hi, @Vaishali04 , the solution is a bit tricky given the fact that filter (selection of a date in the slicer) propogates from slicer to chart,

New Measure =
VAR __date_selected = MAX ( 'Calendar'[Date] ) // assuming there exists a calendar table in your model, and Calendar[Date] is sliced

VAR __period = DATESINPERIOD ( 'Calendar'[Date], __date_selected, -30, DAY )

VAR __inbetween =
    CALCULATE ( MAX ( factTable[Date] ), ALL ( 'Calendar'[Date] ) ) IN __period // slcier must be removed in order to keep all other dates in sight

RETURN
    IF ( __inbetween, [Old Measure] )

I tried you logic but it is giving me only two dates. It will be more helpful , if you could share a sample PBI file for the same.

@Vaishali04 , as you wish, I attached a pbix file for your reference.

It's a simplified project I was once engaged in. It's with more flexibilities to display previous 1 ~ 30 days before a chosen date.
