How to create two lines in a Line Chart

[Singhcooldeep]

I want to create two lines in a Line Chart(Only Need the data where Age is 6 for the device)
1. First line should show the count difference of the Device from previous month where Age should be only 6
NOTE: To get the count difference for each month only last available date should be consider for that month, For Example: For the month of March the last available date is 20-03-2025, so only for 20-03-2025 where device Age is 6 should be consider for the count difference for March, not any prior date should be consider for the month.

2. Second line should show 'Expected Device Count' for the remaining month including the current month till 2025 where Age is 6
NOTE: Attached a raw file to work, however the actual data get refresh on random dates where new Device records add & some got removed.  
Now lest assume we have 700 Device which has Age 6 till 21-05-2025, so for the second line, the logic should be the
(Latest Device Count/Number of remaining months for the current year) which means 700/8= 87 Count should be appear from May to Dec 2025 and by the next month if count get increased or decreased, That supposed to be divide by 7 and so on till Dec.

@v-venuppu Thank you for the help, I just made a little change in the 'DeviceCountDiff'
In RETURN statement i did 'PreviousCount - CurrentCount' & everyhting is working perfect for me just one thing that the 'DeviceCountDiff' line is also showing the data for June month however in my actual data i just have the data till 19-05-2025.(This data for June is actually the latest device count)
