For each diagnostic, the normalized number of uncertain galaxies for which this diagnostic is discordant, when all diagnostics but one agree (squares), all diagnostics but two agree (circles), and only six diagnostics agree (diamonds). Full symbols correspond to uncertain objects classified as H II-like by most diagnostics, and empty symbols correspond to objects classified as AGN-like by most diagnostics.
