Isocon diagrams are useful and perhaps a normalization would work, but
it may be easier to visualize the enrichment depletion diagram of
Gresens. These are generally arranged in some type of order - e.g., low
field strength to high field strength, charge, etc... Of course this is
very similar to what you are considering.
