Resolution
X-axis is Harmonic number, 2 is second harmonic, 3 is third harmonic etc.
Y-axis is Engineering units (Volts or Amps), you can show this by changing the PT or CT ratio.
If the fundamental harmonic (H1) is displayed, the other harmonic measurements would be too small to show any significant data. 35V of 4160V is ~0.8% of fundamental.
