The Bar Graph and Spectrograph modes are the best to work with for accurately seeing how your changes in the Equalizer are affecting your sound quality. Which you use depends entirely upon your own preference. Because of this direct relationship, adjustments on the Equalizer will be more obvious in Bar Graph mode, for instance, than they will be in Wave mode. Wave mode does show your frequency range, but in a vertical format to show the frequency change from a zero mark that runs horizontally across the center. Essentially, it shows how high the levels are for each frequency.
Level is how loud or soft the frequency is.
The Wave mode will be affected by the changes you make in the Equalizer, but reading it does require a little more practice. Adjusting the frequencies that seem overpowering can correct this problem.
