This is nice. Always looking for sample code to produce heat maps. I'm using SAS 9.4 for Windows (M7), and it ran fine there. Then I tried the code in SAS Enterprise Guide for Windows (version 8.3), also on my computer, and my output was just was the outline axis text, all together on one line - no chart. The LOG showed that the code ran, but showed no error. Do I need a more recent SAS Enterprise Guide build, perhaps?
