Primary Symbology > Unique Values > Expression Builder

Hello,

I need some help building the following pseudo code expression for unique value symbology, expressed in Arcade:

Pseudo Code:

list1 = ['a', 'b',...] list2 = [ 'w', 'x',...] if field1_val in list1 AND field2_val in list2: return 1 else: return 'other'

Much appreciated.

Tyler

We can use Includes to check whether the values are present, than Iif to evaluate the two together:

var list_a = ['a', 'b', ...] var list_b = ['w', 'x', ...] var a = $feature['attribute_a'] var b = $feature['attribute_b'] var in_a = Includes(list_a, a) var in_b = Includes(list_b, b) return Iif(in_a && in_b, 1, 'other')
