Hi
I work at a university and my management want to do analysis based on (4 month periods) since our activity makes more sense during these period instead of quarters.
Is it possible, maybe easy?, to add options for that?
I have created custom fields so i can view them on 4-month periods over time, but I cannot use the trend chart unless I pick any of the existing time periods (month, week, year etc.)
I think you can still use Trend but you may have to switch up how your Question is structured. You can create a customer column that determines if a date is in the prior 4 months or not. Set your overall filters to 8 months, then group by the interval. If you return a max date int he summarize block you should be able to use the Trend viz.
Interval function:
Question structure:
Trend:
Is this close to what you're trying to accomplish?
Alternatively, create a Date table that contains your period dates. Easiest approach is one row per day with the corresponding period name.
That way, when the University decides to change how they want the dates structured, you only have to change it in one place.
Yes, I'm scarred from working with universities
