Understanding the Videographs requires careful, repeated viewing because they track responses on a number of different levels.  It is important to consider not only the horizontally moving blue and red lines which represent the running average, but also the “histograms” - the vertical bars, at the bottom of the screen.  

The histograms show the percentage of listeners responding to a sample at each of the levels of the 1 to 9 scale. Responses at the lower end of the scale (1, 2, 3 and 4) indicate the proportion of listeners likely to tune-out when that sound is played - even when there may be some listeners responding positively. This provides perspective on whether the average represented by the line graph is the result of consistent reactions that is mostly positive or negative or mixed reactions on the scale (i.e. some positive scores and some negative scores averaging out to low appeal).
