Observed occurrences compared to total possible occurrences (date)

[andrew06074]

I have the following dataset

For each object I want to mark each date that the object had an observation so I can calculate its occurance ratio compared to time

For instance looking at 3/5-3/7 I would want the following table

Thank you!

Hi , @andrew06074 

According to your description, you want to generate a table from the dataset.

Here are the steps you can refer to :
(1)This is my test data:

(2)We can click "New Table" and enter this:

Table 2 = ADDCOLUMNS( CROSSJOIN( CALENDAR(DATE(2023,3,5),DATE(2023,3,7)), VALUES('Table'[Object])) ,"Occurred" , 
var _t = FILTER('Table','Table'[Date] = EARLIER([Date]) && 'Table'[Object] =EARLIER('Table'[Object]))  return
IF( COUNTROWS(_t)>0 , "y","n"))

(3)The result is as follows:

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI!
