"Vary Symbol By Attribute" is not grabbing all values?

GB_MattPanunto_GISS — Fri, 23 Jul 2021 18:14:10 GMT

I'm trying to vary the transparency of a layer by an attribute field. The values in my field range from 5-179 (the values represent the age of a data point, in hours). However, when I specify the field, it only seems to detect values between 140-178.

The field type was originally a Double, but I have since converted the values to Short in order to simplify them. That didn't seem to make a difference. Is there some kind of limitation at play here that I'm not aware of? I am running ArcGIS Pro v2.7.3.

I can't reproduce it in ArcGIS Pro 2.8.1.

Please ensure there is no unsaved edits.

What happens when you click "Refresh Values"?

Hmm, I just found a computer with v2.8.1 and gave it a shot, but had the same issue. I've attached the dataset here if you want try taking a look. To clarify, I'm trying to vary the transparency by the AGE_HOURS field. Thanks!

Looks like it has a limitation of upto 10,000 records. So, it took the values of first 10,000 records sorted by ObjectID. I couldn't find any documentation on this limitation.

@KoryKramer : Is this a known limitation, or a bug?

For a test, I dissolved the Feature Class based on "ACQ_DATE" and "ACQ_TIME", assuming the "AGE_HOURS" and "AGE_DAYS" are same for this combination (*but you will lose other attributes which differ within this combination, e.g. "BRIGHT_TI4", "FRP", etc.). The result is only 319 multipoint features.

Then, values for varying the symbology looks fine.

Wow, good sleuthing! It's interesting that the ESRI Livefeeds feature layer of the same data (even larger, actually) does not seem to have this limitation. As a Living Atlas product, maybe it has some additional data privileges?
