3 Month Average of Market Share %, Line Chart

[jonp]

Hello, I’m trying to create a line chart that tracks a 3-month rolling average of a percentage over time. I can create a line chart that tracks the count of sales over time, below, but I need to track this as percentage comparison for each month, and a 3-month rolling average of that percentage.

This is the example of the data…

Essentially, it needs to be like the chart below (tracking the percentage market share over time), but a line chart, and a 3 month rolling average for each month...

Thanks

Assume you already have count formula

formula 1
Count1 = Count('Company'[Count])

formula 2
Avg Amount = 
calculate(AverageX(
    VALUES(Table[Date])  // count till Day level
    , [Count1]
),DATESINPERIOD('Date'[Date Filer],ENDOFMONTH(Sales[Sales Date]),-3,MONTH))

Values will group data at that level. Like here at day level.
