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?
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
