Primary Symbology > Unique Values > Expression Builder

TylerT

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')
