Greetings Matt!

The values on the breakpoints are determined by the position of
the breakpoint along the legend, proportional to the min and max 
of the Range. Changing the minimum and maximum of the Range changes
the break point values. I think the only way you can ensure the 
break points are at a particular value is to make sure the range 
on the colorbar with the new data is the same as the range you used
when you created the colorbar.

Can you let me know if the colorbar works as you want if you set the
original range?

Cheers!

Sean
