Transform weekly data into hourly data

So the situation is as follows, I have weekly records of events and i want to make it hourly, logically every hour will have the same value, that corresponds to the whole week, but i need it to be hourly so i can plot it with other hourly data i have. Any ideas on what to do? I tried creating a table having the specified beginning and ending dates i need and every hour of these days, but i am not able to copy the data from the other tble that contains the weekly data, i dont know how to use dax for it, am i missing something? Is there a easy way to do it?

Hi  @artp3642  , 

 

I am sorry i couldn't entirely understand what does your weekly record look like and hourly look like?

 

generate(filter( generate(summarize(Date, date[Date], Date[D WeeK end Date]), Table) , [Week End Date] = [D WeeK end Date]),[Hour Table])

The first Date means a table. It is the first argument of summarize().

 

Actually, you can create a Date table contains Year,Month,Day, Weeknum,Hour. Then create a relationship between Date table and Fact table, which is one to many and depended on Date/time column.

By this code:

Date = GENERATESERIES(DATE(2022,1,1),DATE(2022,12,31),TIME(1,0,0))

Then you can plot with other hourly date.

 

Pbix in the end you can refer.

@artp3642 , Assume you have data with week end date , some number

 

create a date table with week end date ,

 

Hour Table = generateseries(1,24,1)

generate(filter( generate(summarize(Date, date[Date], Date[D WeeK end Date]), Table) , [Week End Date] = [D WeeK end Date]),[Hour Table])

 

if needed divide the value column by 7*24 to allocate

@amitchandak 

so first i create a table clalled hour/-table and then create a column using the followeing expression? 

generate(filter( generate(summarize(Date, date[Date], Date[D WeeK end Date]), Table) , [Week End Date] = [D WeeK end Date]),[Hour Table])

I didnt understand what Date in the first argument mean, is it a table, or what, and neither Table as the last argument
