1. A system for displaying graphical information indicative of a plurality of material characteristics for a portion of a part under test, the system comprising: an energy emitter that directs x-ray energy at a selected portion of a part under test; a single stream of diffracted x-ray energy formed by interaction of the x-ray energy with the selected portion of the part under test, the single stream of diffracted x-ray energy being indicative of a plurality of first order material characteristics of the part under test; an energy detector that detects the single stream of diffracted x-ray energy; a controller configured to analyze the single stream of diffracted x-ray energy and determine a first material characteristic and a second material characteristic for the same portion of the part under test and from the same single stream of diffracted x-ray energy, the controller being further programmed to form a first graph relating to the first material characteristic and a second graph relating to the second material characteristic; and a display on which the graphs are generated for viewing and for facilitating simultaneous visual comparisons between the information contained in each of the graphs.
