The spectrum window controls allow you to zoom in (< >), zoom out (><), shift the zoomed
view to lower- and higher-energy channels (Pan Left/Right), toggle between logarithmic (Log)
and linear (Lin) vertical scaling, and move the histogram window’s green marker line to view
the energy and count information for individual spectrum channels. Figure 24 shows the various
controls and features.
