When multiple filters are enabled, the graph indicates the focused filter result (independent
of other filters) in the color of the filter row in table. The composite response, the combined
effect of all filters not bypassed, is always displayed in red.

Above the graph, each filter has a "handle" (circled in red above) placed directly above the
cutoff or center frequency whose number corresponds to the filter number (outlined in red).
Click a handle or click the table row to bring focus to that filter. Click+hold+drag the handle
horizontally to change the cutoff or center frequency.
