It would be better if we can compare date field with “current date and time” in chart and display time between them.
There are many use cases. For examples…
Show how many days until due date
Show records which are unchanged for some time
Show list of devices which exceed next inspection date
I am excited to share that we have CurrentDateAndTime() function in the Expression Editor in Analytics where you can actually compute this, you should be able to do all of the examples you have listed. Feel free to give it a try, and let me know if you have any questions.
