In my plotting routines at:

	http://space.mit.edu/home/mnowak/isis_vs_xspec/

I've also added a "user unit", such that:

	isis> Plot_Unit("user_unit_a");

will basically say, treat these input data as being in the same order  
as Angstroms, but apply  a preset X & Y scaling when plotting the  
data, and also apply a preset set of X & Y labels when plotting bin  
integral or plotting bin data.

I've used ISIS often enough to fit things other than counts/Angstrom/ 
sec that it was worth automating the plotting a bit.
