This multi-panel graph presents high-resolution electron energy-loss spectra from a GaN surface. The graph effectively utilizes Origin's strong layering capability. The three main panels present measured data (red filled circles with vertical drop-lines) and calculations (solid blue line) at three beam energies. The x-axes of these panels have been linked together, and axis breaks have been introduced to present relevant data over a wide range of energy loss values. The insets in the three panels display a section of the data that shows the most variation with beam energy (E0). The markers in the bottom two inset panels indicate a shift in the mean value of the measured and calculated distributions. The graph has been annotated with text that includes superscript and subscript characters.
