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 different first order material characteristics of the part under test; an energy detector that detects the single stream of diffracted x-ray energy and forms raw data from the single stream; a controller configured to analyze the raw data and determine a first one of the plurality of different first order material characteristics comprising stress and a second one of the plurality of different first order material characteristics comprising shear stress for the same portion of the part under test from the raw data, the controller being further programmed to form a first graph relating to the stress and a second graph relating to the shear stress; an electronic display on which the graphs are generated for viewing, the first graph being positioned adjacent to and non-overlapping with the second graph, the positioning of the first graph with the second graph facilitating substantially simultaneous visual comparisons between the information contained in each of the graphs in order to determine a condition of the part under test directly from the visual comparisons without the need for further analysis or manipulation of the graphs.
