Data availability across frequencies with data/no data for the same period
When a dataflow has data for 2020-Monthly but no data for 2020-Annual, then if for instance 'End-date' is 2020-01, and if I change the frequency selection from Monthly to Annual, it results in 2020 being greyed but also selected.
Instead, in this case, End date should be emptied.
Technical considerations
- as shown in the below diagram, when users request for data in viz page, by applying a filter selection, availability and data query are both sent in // at the same time. Achieving the above request would mean changing this default behavior by sequencing both queries. This means increasing the time to display any result.
