colorAxis Not Working for Geochart

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a region GeoChart
2. Try to change colorAxis as directed

What is the expected output? What do you see instead?

I was expecting the gradient for my choropleth map to change to red, but 
instead it remained the same default green color.


What operating system, browser and version are you using?

I am using a Mac OS 10.8.5, running the latest versions of both Chrome and 
FireFox (both of which have the error).
