It depends upon the type of music you choose to run on the visualizer, try to run music with high frequency and you will see all the bars appearing in the visualizer, because the visualizer catches the frequency and after analyzing the music frequency it creates the bars matching the frequency, the higher the frequency the higher will be the bars.
