Scatter plots of various parameters for the three types of ARs. The horizontal axes represent the peak unsigned magnetic flux Φ_p, while the vertical axes display the (a) accumulated helicity ΔH, (b) accumulated energy ΔE, (c) normalized helicity ΔH/${\mathrm{\Phi }}_{\text{p}}^2$, (d) emergence time t, (e) helicity injection rate ΔH/t, and (f) energy injection rate ΔE/t. The mean values of the parameters for the three types of ARs are listed at the top of each panel.
