Large dataset - symbology won't symbolize on unique

nimitz

Hi all,

I'm trying to symbolize a large dataset(20k records). The column I want to symbolize has 3 unique values. However, in the table of contents, when I select that column, only 1 of the 3 values shows up. Is this too big of a dataset for this? I'm going to try in Arcmap just to check, but this is a head scratcher.

Arcgis Pro, 3.5, Win 11.

ok, this solved it. You need to click on "add unique values". Weird. Why couldn't it load from the symbology in table of contents?

Maybe you have unsaved edits?

I didn't do any edits. I just tested this in ArcMap. It does work. I'm not sure what I'm missing. I've done this on other datasets, but this is weird.

If you add the missing values do they render correctly? Might be an over-optimization from Pro that's skipping too many features when it builds a list.
