LegendBench - Guide Reading: leaderboard
Legend parsing in LegendBench (Zhang et al., 2026): questions that ask the model to read the mapping a legend states, such as which color or marker stands for which series or what a color bar encodes. Accuracy in percent; higher is better.
Metric: Guide-reading accuracy (%; legend-parsing questions: extract the mapping the legend makes explicit; LegendBench snapshot of 26,689 legend-centric chart questions generated from 900 base charts with counterfactual legend variants; the same prompt template and hyperparameters for every model). Source: arxiv.org. Saturation forecast: Estimated already saturated. 12 models tracked.
