The surface distributions of magnetic flux for the Sun-like star with P_rot = 27 d (top panels), P_rot = 9 d (middle panels), and P_rot = 2 d (bottom panels), near the activity minimum (left panels) and the maximum phases (right panels). The colour scale for the magnetic field strength saturates at  ± 5,30, and 75 G for top, middle, and bottom panels, respectively. The corresponding time-latitude diagrams for the azimuthally averaged magnetic field strength are shown in Figs. 5c, 7c, and 9c.
