If you combine the 2 images into a "cube" and run PCNTR on it, then you 
can plot the two on the same plot.  If you RESCALE the one you want with 
factor=-1 before MCUBE, then the contours of that one will be dashed.
Chapter 6 of the CookBook on page 30 shows how to do this (although the 
emphasis is on making color pictures).
