Symbology base on multiple fields Coded Values

Heberlyeng — Tue, 04 Jun 2024 18:55:37 GMT

I am trying to create an expression that will return all coded values from two fields (STATUS and Funding_Source) so that I can symbolize based on the results.

For example. if I have Status's coded values as:

A, B, C

and Funding_Source as:

X, Y, Z

I want symbology for:

A-X, A-Y, A-Z, B-X, B-Y, B-Z, C-X, C-Y, C-Z

If I use concatenate($feature.STATUS,'-',$feature.Funding_Source)

I only get values for populated fields not all coded values)

I tried building an arcade expression:

var STarray = Array(0)

var SD = Domain($feature, 'STATUS').codedValues

var FD = Domain($feature, 'Funding_Source').codedValues

for (var i = 0; i < Count(SD); i++) {

for (var a = 0; a < Count(FD); a++) {

Insert(STarray, 0, Concatenate(SD[i].code,'-',FD[a].code))

}

STarray

It returns an array of exactly what I want, but it makes 1 symbol with a legend value of the entire array output.

Is there a way to symbolize on two fields and get all coded values?

Thanks much,

In Map viewer symbology, click Expression:

I used:

var SD = DomainName($feature, "Status") var FD = DomainName($feature, "Funding_Source") return Concatenate(SD,'-',FD)

Which, since I already had several of the combinations in the data, it automatically sets up those class values.

Then, I added a new polygon "B-Y" since it wasn't already in the list, but it symbolizes by "Other".

Then, select the three dots and Add Value:

And enter the value(s) you want (here I add the missing "B-Y")

And it now symbolizes by the newly added value instead of "Other".

Thanks for the input. This is what I pretty much ended up doing. Just would be nice if this could happen without having to add the remainders manually.

Thanks again.

If I have to do this with many values, I find it easier to just create a features for each value off to the side before I create the symbology.

Once the symbology is created (and saved) you can delete the temp features.
