Slicer selects latest date, need to show Sales for last X days

[skashifz]

Hello,

I am new to Power BI. I have developed a Dashboard, which is based on FACT table, which have ratings us and of 4 Competitors for every date, and table also contains Week To Date ratings (Week starts Sunday). I have 1 Date Slicer in which i select 1 Date. There are 2 Stacked Bar Graphs, 1 shows Day ratings, other shows Week To Date ratings. Now i need to add another visual (Line Chart) to same dashboard to show last 30 day's ratings (ratings of each day individually). How can I achieve, because it is showing ratings of only the day selected in Slicer ofcourse. Any help of info or reference to older blog about this situation will be highly appreciated.

Thanks in advance

@skashifz you need to add an explicit measure for sales amount that honors this disconnected table selection and use that measure in the above visual

Sum Sales Amount = 
CALCULATE ( 
    SUM ( FactInternetSales[SalesAmount] ), 
    TREATAS ( VALUES ( 'Dim Date Slicer'[FullDateAlternateKey] ), DimDate[FullDateAlternateKey] ) 
)

@parry2k Thank you very much for the effort. The problem is, that top chart is now NOT showing value for the date selected by Slicer. It is showing sum of all dates (or upto selected date).

@skashifz No sample data so can't be specific but should be something along the lines of:

Measure =
  VAR __Date = MAX('Table'[Date])
  VAR __30DaysAgo = __Date - 30
RETURN
  AVERAGEX(FILTER(ALL('Table'),[Date]>=__Date && [Date]<=__30DaysAgo),[Rating])

@Greg_Deckler will this give average of all previous days, or will it give value for each day seperately so i can graph trend for all these previous days ? May be I should work to get a small sample pbix to show this ?

@skashifz 

pls provide the sample data and expected output.

@Greg_Deckler , @ryan_mayu  I have attached dropbox link to the pbix file based on AdventureWorksDW. The Line Chart is showing one date on the axis, I want to show last 30 days on x axis and Sales values for those dates in this line chart.

Hope I cleared myself, and Thank you so much for the help. Really appreciate it.
