Comparison between the breaks found for the log(N/O) radial gradients (y-axis) and 12+log(O/H) radial gradients (x-axis) in our sample. Green dots correspond to LINERs showing one break in both gradients, whereas red dots correspond to LINERs showing two breaks. The solid black lines represent the one-to-one relation, the dotted lines represent the median offset, and the shaded gray area the deviation.
