Burndown chart

I am trying to create a card that shows a burndown representation of my data. My data has to do with Courses, estimated time to Complete (Duration), and Actual Hours to complete. I think to create a burndown I need a new column that gives total Duration per year of all courses due that year and then I want to be able to subtract hours to complete for each month and show burndown over the year. Anyone have any thoughts on best way to do this?
Course | Year Due | Month Due | Duration | Hours to Complete |
---|---|---|---|---|
A | 2023 | December | 1 | 0.5 |
B | 2024 | February | 1 | 1 |
C | 2024 | March | 1 | 1.5 |
D | 2025 | January | 2 | 1 |

You can add your group names to the partition list
PARTITION BY `Year`, `Other Group`

You can get the total for each year with a window function:
SUM(SUM(`Duration`)) OVER (PARTITION BY `Year`)
You can get a running total with another window function:
SUM(SUM(`Hours to Complete`)) OVER (PARTITION BY `Year` ORDER BY `Month`)
NOTE: Your Month needs to be an actual date or a numerical representation to be sorted properly; otherwise, it'll sort alphabetically and be incorrect.
Combining these two, you get your burn down:
SUM(SUM(`Duration`)) OVER (PARTITION BY `Year`) - SUM(SUM(`Hours to Complete`)) OVER (PARTITION BY `Year` ORDER BY `Month`)

Thanks that is working. How can i modify formula if i want to have different lines for different groups? I tried putting the groups in series on chart but didnt work well and the lines for each group were not connected and is just a bunch of data points
