Symbology based on 2 fields?

KorySteele — Wed, 15 Apr 2020 20:21:17 GMT

In the legacy ArcGIS, I could set up symbology so that when 2 fields had values, the color of the line would change.

Specifically, we are doing stormwater mapping. I would like the line for the pipes to change color when both the up and down stream inverts have been inputted. I'm having trouble setting this up in Pro to begin with, and then I realized it may not even transfer to AGOL or Collector to begin with. Is this even possible?

Hi,

create an "New Expression" with Arcade in Symbolgy. You can use two fields by concate them

Concatenate(arrayOfFieldsOrValues, '/')

Cheers

Karsten

Kory,

You could also set it up in ArcGIS Pro like the following:

Choose unique values for symbology and set an Arcade expression of your choice to get the job done.

Given the description you gave, I used.

If (IsEmpty($feature.upstream)) {
return 'No Upstream'
}
Else if (IsEmpty($feature.downstream)){
return 'No Downstream'
}
Else {
return 'Complete'
}

Then in the Symbol Pane I added the possible values that the Arcade expression could return. (you need at least one feature to do this, but you don't need all possible types)

Type the values in exactly as they would be returned from your Arcade Expression.

Then Share as a webmap from ArcGIS Pro.

As you work in Collector the map will symbolize (and label if you use the expression there) as defined by the Arcade.
