Optionally trim sankey start date

[AlphaJack]

Hi Andreas, thank you for this wonderful Fava extension.

I started using Fava/beancount way before my first job. Therefore, the figures I see are way different from the reality of the last 9 months. I would like to trim the Sankey diagram to the last 9 months, to get a realistic overview of my saving rate and recent expenses.

If I specify a date, it should be used in both the query and the days calculation. If I only add it to the query, days still reports the number of days since my very first transaction, way before 9 months ago.

My solution is to:

• add AND date > 2023-02-01 to the query
• replace new Date(ledger.dateFirst) with new Date("2023-02-01")

Is it possible to specify the date once as a parameter of the query, the JS code and maybe also the title? Related to #23

hi @AlphaJack, can you use the fava time filter (in the top bar) for it? When you specify month-8 - month it should give you the results you want, without any modification of the sankey chart.

Personally I'm using this shortcut to show the last 12 months (excl. the current month, as I usually don't have up-to-date data for the current month):

1992-01-01 custom "fava-sidebar-link" "Last 12 months" "/jump?time=month-12 - month-1&interval=month"

Thank you, this is even more versatile!
