Radial metallicity profiles and metallicity gradients calculated for our sample of dwarf galaxies. Top: smoothed [Fe/H] profiles as a function of SMA radius as obtained from the GPR fitting method in units of the 2D half-light radius (left) and as a function of physical radius (right). The radial metallicity profiles have been normalised to their value at R = 0. Dwarf galaxy names are as in Table 1. Bottom: distributions of the calculated metallicity gradients in the same units as in the top panels; bin widths were obtained following the Freedman-Diaconis normal reference rule.
