1. An X-ray analysis apparatus having a function for enabling a plurality of measurement methods to be implemented, comprising: measurement software for implementing each individual measurement method and acquiring X-ray measurement data from X-rays detected due to the implementing of the individual measurement method; analysis software for performing a predetermined analysis on the measurement data and acquiring analysis data; reduced-size-image-creating means for creating a reduced-size image on the basis of each item of the measurement data and the analysis data; analysis-icon-creating means for creating an icon for denoting the analysis software to which the measurement data or the analysis data indicated by the reduced-size image created by the reduced-size-image-creating means corresponds, wherein said measurement data indicates a measurement method under which said measurement data was acquired; and image display means for displaying the reduced-size image and the icon on the same screen while indicating that the reduced-size image and the icon are correlated, wherein: the X-ray analysis apparatus irradiates a sample with X-rays released from an X-ray source and then detects, by an X-ray detector, a diffracted X-ray, a reflected X-ray or a small-angle-scattered X-ray each given off by the sample; and the image display means displays a joint image indicating that a correlation is present between the reduced-size image created by the reduced-size-image-creating means and the icon created by the analysis-icon-creating means, the icon denoting the analysis software to which the measurement data or the analysis data indicated by the reduced-size image corresponds.
