Probability density function (histogram and its respective curve) for the magnetic field strength (left plots) and LOS velocity (right plots) over the area of the magnetic flux concentration (region marked by the purple contour in the first column of Fig. 2) for the three defined evolution phases: the drain phase (between t = 0.0 min to t = 2.3 min), the upward-flow phase (between t = 2.8 min to t = 5.13 min), and the relaxation phase (between t = 5.6 min to t = 7.0 min). The information included in the labels applies to both panels.
