Comparison of the our T_e-based metallicities with strong-line metallicities in our galaxy sample, as a function of radius. Here, we use the N2 Marino et al. (2013) strong-line calibration. The N2 values (grey) are compared with individual T_e[N II] metallicities (red) and T_e[N II] stacked metallicities (black). For context, the subsample of individual regions with T_e[N II] detections are highlighted within the N2 measurements in light blue. Linear radial gradients are fit when there are at least 5 measurements that cover at least 0.5 r_eff. Galaxies are ordered from low (top) to high (bottom) stellar mass, and axis scalings are not matched between galaxies.
