Lze v ArcGIS Online měnit symboliku podle data poslední aktualizace prvku?

JessicaKirby2

Potřebuji, aby hostovaný prvek měnil barvu podle data, kdy byl naposledy aktualizován. Například zeleně pro dnešek, žlutě pro poslední 3 dny a červeně pro starší než 3 dny. Je to možné? Nenapadá mě jiné řešení než pomocí skriptu v Pythonu stáhnout data, zpracovat textové pole a znovu je publikovat. Hledám spíše řešení v „reálném čase“, které nevyžaduje stahování hostované služby. Nemám server, takže nemohu publikovat geoprocessingový skript. Říkám si, že přece musí existovat způsob, jak k tomu využít data s časovou složkou?? Nevíte někdo?

I have not attempted to use the new programming language called "Arcade", but I had seen this at the User Conference this summer and it looks like this could potentially help you? I am not a hundred percent sure, but it could be a way. Again, I have not used this, but they were completing some similar tasks during one of the demos.

Hi Kelly,

Thanks for leading me to the blog

I see the example:

var t = Hour($feature.Created_Date); When(   t >= 22 || t < 6, "Night",   t >= 6 && t < 11, "Morning",   t >= 11 && t < 13, "Midday",    t >= 13 && t < 17, "Afternoon",   t >= 17 && t < 22, "Evening","Invalid date" );

I've been trying to get a way to change your script to work for what I need. Below is my attempt, but I am getting an "Invalid date" result for all results.

var d = Date($feature.EditDate); When(    d == Today(), "Groomed Today",
   d >= Today() && d <= Today()+3, "Groomed Recently (Within Last 3 Days)",
   d >= Today()+4 &&  d < Today()+7, "Groomed (Within Last Week)",
   d >= Today()+7, "Not Groomed",
"Invalid date" );

What am I doing wrong? Any help is appreciated!
