This due to an improper zrange being specified. If you save the gnuplot commands and remove the zrange line it should work properly. 

To me honest, I was worried about that, but when I tested it (switching between a standard gnuplot 4.2.3 and one patched for interpolate colors) ... all went well. I doubt the difference is that I'm running 4.2.3. It is more likely I did the testing wrong.
