Filtered Bar Chart screen
For the filtered bar chart screen, the dominant characteristic of this screen is the multi-element bar chart. The chart displays measurements in each filter
band and broadband values for both meters. For octave band analysis, the screen contains 13 bars (11 for filters and 2 for broadband), and for third-octave
analysis the screen contains 35 bars (33 for filters and 2 for broadband) of measurement values. The bars appear (and usually fluctuate) if the measured
value for the bar is above the minimum value for the selected measurement range.
