Symbolize specific values from field

Bud — Wed, 30 Nov 2022 17:51:37 GMT

Using a point shapefile, I want to symbolize features based on a field: P_COMMOD.

I only want to symbolize certain values:

ACTINOLITE
AMETHYST
ANTHRAXOLITE
ANTIMONY

Is there a way to only symbolize certain values like that? For example, is there a way to add or remove specific values from the symbol list?

I would prefer to do it in a single layer, rather than using separate layers with separate definition queries and separate symbology.

Thanks.

ArcGIS Pro 3.0.3.

Above your list of symbol classes, you can click the "+" to manually add symbol classes. When I have situations like this, I delete all the symbol classes and just add the specific ones I need.

Remove all:

Manually adding classes:

If the value is not present in your layer, you can also manually create it there.

Thanks! That works.

Do you know if there's a way to symbolize All other values or Null values?
(Similar to what we could do in ArcMap.)

It's that first option in the dropdown:

If you want your "all other" to be separate from your nulls, I'm not sure there's a built-in way to do it, but a quick Arcade expression would handle it.

For my notes, regarding the Unique Values symbol option:

In ArcGIS Pro, nulls get included in the "all other values" symbol class.
- That's different from how ArcMap works; nulls get their own symbol class. Screenshot.
But Empty values don't get included in "all other values"; they do get own symbol class.
