Is it possible to setup a filter that will do a count-down to a date so for instance if I have an event that's happening in Febuary and I want it to take the numbers from today and change the Day's( and subtract one from it. so for instance. I have a Circle Chart that show numbers from 1 to # of Day's out from the event. I have to manually go to the viz and change the day's out -1 so if it was Monday and I had the filter at 1 - 90 then on Tuesday I have to change the 90 to an 89 and republish the viz. This is a huge pain. Is there anything I can look at that will make this so much easier?
