Rank curves of carbon substrates with fixed orders to show responsiveness and inconsistency in genotype-by-environment variance. Each line represents the relative growth of a genotype across different substrates. The order of substrates at each temperature is ranked by decreasing growth performance of the genotype with the highest mean growth values across all substrates. The discrepancy in slope among genotypes represents responsiveness (unequal variances on different substrates); and intersection of the lines represents inconsistency
