trailing previous 30 days + week of date selected in a Area line Chart

[X19203659]

Hi team,

I would like to get a similar final result as shown in graph below:

I am currently using Power Kpi 2.0.0 to show this area line chart.

As you can see the 7 lines refer to a specific day of the current week (Monday, Tuesday, etc.) and the area part is the average of the previous 30 days ("Prev.Week").  The x axis only shows the time of day.

I would like to be able to select any date in the past and based on this selected date, show the week of this date ie. 7 lines (for each weekday) and also show the average of the previous 30 days (ie. month) prior to the week (ie. 7 lines). 

To achieve this I have the below data:

- "Attribute" = Location Name

- "This week" = name of the day ("Monday", "Tuesday", etc., "Prev.Week")

Many thanks in advance for your help!
