Abstract: A simple and intuitive graphical method is presented for producing a summary overview of experimental results of a common measurand, e.g. in the frame of an inter-comparison. The ¿PomPlots¿ display (relative) deviations of individual results from the consensus value on the horizontal axis and (relative) uncertainties on the vertical axis. The z-scores, z=1, 2 and 3, are represented by diagonal lines, creating the aspect of a pyramidal structure. The most accurate and precise measurement results should be situated close to the top of the pyramid. The plots are used to visualise data from the BIPM Key comparison Data Base (KCDB) on primary radioactivity measurements.
