Evolution of different measures of shape over time for 15 bar-like galaxies. Lines show the axis ratios b/a (blue), c/a (red), the triaxiality parameter T (green), the rotation parameter f (magenta), and the bar mode A2 (black). Galaxies are identified by their subhalo ID numbers at z = 0, shown on the right of each panel. Vertical dashed lines indicate the time of bar formation.
