Bar and Area chart - how to change format (color/dotted line/highlight/etc) if it's in future date

[alya1]

Hello, 

I saw some solutions for similiar issue but my x-axis is a hierachy with Year and MonthID (for example. 2024-07, 2024-08, etc) with no date. Both of these are stored as text. I would like the formatting change to carry over when I drill up/down/expand hierachy please.
Area chart is summing as it goes to year and bar chart is averaging as it goes to year. Any formatting change is ok (different color/different line type/highlighting the background/etc) to show it isin (MonthID)/contains (Year) forecasted data in a future date.

Below is a sample of the data:

Year	Month	MonthID	does it have historical data?	To be graphed
2024	05	2024-05	yes	10
2024	06	2024-06	yes	12
2024	07	2024-07	yes	13
2024	08	2024-08	no	11
...	...	...	...	...
2025	02	2024-02	no	15

Thank you so much!
