What is the problem or goal the end user is trying to solve or accomplish?
Currently, when the Time Grain is switched, the tooltip will display the first date of the selected grain. So, if it is Weekly, it will display the first date of the week; Monthly, the first date of the month; and so forth. Intuitively, the granularity of the tooltip will follow the selected Time Grain. So, if it’s monthly, it will show the Month name, Quarterly will show Q1, Q2, etc.
How are they solving it currently?
Change the Tooltip Time Format from Adaptive Formatting to the desired format.
What is the recommended solution by the Customer?
Switch the Tooltip Time Format according to the selected Time Granularity
