I have a raster layer I interpolated from when I ran the Getis-Ord_Gi* Hotspot tool.  My bosses at work really are interested in me trying to get it to resemble the map pictured here .  They want the higher value clusters  to be displayed like the "islands" shown in the example, but also have all the other values not visualized.  I really just cant figure out how I can symbolize a few parts of a raster, but not the lower values at the same time to achieve this "islands of heat" effect. Any suggestions?

I'm afraid your linked map does not exist.

Matt, Draw the raster using a classified symbology. choose the number of breaks, go under the Classify button, choose Data Exclusion, and exclude the values below the lowest level you wish to show, say 0-100. then, only values above 100 will be displayed.
Alternatively, create a classed post, and set the range you do not want to show to have no fill. I hope this answers your question!
Regards,
Jim
