Burtin Bokeh - questions around the circular axis and labels

Hi All,

With the burtin.py, the figures from the inner to the outer circular lines are decreasing in values e.g. 100, 10, 1, 0.1, 0.001 as shown in the sample on the website.

Does anyone know how to modify the burtin so that the values increases from inner to outer lines e.g. 0.001 to 100 instead of the other way round?

Here is the link to the sample:
