Use Arcade in Chart Variables
I would love to be able to use Arcade expressions to define/reclassify categories, numeric fields, and splits. Here's one example - my dataset doesn't have a year field, but it has a date field which contains a year (though does not show up in the dropdown at all). I'd like to see fatalities by city and year, so my only option right now is to create a year field and calculate it that way. This is a hosted feature layer, so that also requires making my own copy of it. Arcade could help take these steps out simply by entering the expression Year($feature.CRASH_DATE) in the Split by field.
Hi @wayfaringrob ,
This is a great idea--in fact, adding Arcade expressions to charts is on our mid-term roadmap and should be available in an upcoming release! Here's a sneak peak where I've created an expression ("CRASH_YEAR") to extract the year from a date field and split the bar chart by this expression:
There will likely be limitations regarding which chart types and chart properties support Arcade expressions, but your use case should be covered.
Thanks,
Chris
