Hi Joel,

I see, thanks for the clarification and the example.

What you need is to a) explicitly disable the tick scaling (which is 
unrelated to the number printing) and b) to fix something in the 
exponential style:

using

colorbar style={xticklabel pos=upper,/pgf/number format/sci,/pgf/number 
format/sci e,scaled ticks=false}

does what you want (from what I understand).

The 'sci' key ACTIVATES the scientific display whereas 'sci e' 
CONFIGURES how an activated scientific format is displayed.

The 'scaled ticks=false' key disables the extra '*10^6' node and the 
scaling.

Best regards

Christian
