1. A method for displaying graphical information indicative of a plurality of material characteristics for a portion of a part under test, the method comprising: directing energy at the portion of the part under test; detecting resultant energy from the portion of the part under test, the resultant energy formed by interaction of the directed energy with the portion of the part under test; forming a plurality of graphs based upon the resultant energy, each of the graphs relating to a separate one of the plurality of material characteristics; and displaying the plurality of graphs in a manner that facilitates substantially simultaneous visual comparisons between the information contained in each of the plurality of graphs.
