I input a number of raster bands into the Iso Cluster Unsupervised Classification tool and asked for 5 classifications and specified a signature file to be created. The tool ran for a while and then completed. It put a raster in the Table of Contents that was a single solid color. I looked at the signature file and it had 5 classifications. I tried to look for a way to change the symbology of the output raster to see the classifications, but couldn't find it. How can I get a visualization of the classifications in the actual output raster?
