Hi all,

I'm new to ArcGIS Pro and have been utilizing the pixel editor to alter the values of some raster data I've received. While previously using ArcMap I was able to use the symbology to obtain the pixel count of each unique value along with the pixel size to calculate the area of each unique value but I've noticed it's not shown under symbology in Pro. Wondering if there is another method to obtaining the count in ArcGIS Pro?

I appreciate the quick reply Dan! Should've been more specific sorry, when I try to add any unlisted values in Pro there is nothing to add (even though it's the same map file, I've imported to Pro). It just gives me an error saying the operation could not be completed.

unlisted?  Did you alter the raster after the initial symbolization?

In the interim try step 4

Apologies Dan I had selected the green plus sign opposed to the 'more' drop down. Appreciate the solution!

The only odd thing is that it doesn't give a count for the top value but toggling the order from ascending to descending allows me to obtain both values (1 and 6).
