Abundance ratios for which a significant level of correlation is found. Only clusters closer than 1 kpc and with more than one star are plotted. Error bars for the x-axis are usually smaller than the point size. The best-fit model is overplotted in black (the resulting slope written in each panel in dex Gyr⁻¹), and the light gray lines correspond to the sampling of the MCMC. Element names are colored depending on the chemical family they belong to.
