ChartJudgeBench - CPA Data Encoding: leaderboard
The data encoding criterion of ChartJudgeBench Chart Perception Alignment (Wu et al., 2026): 164 chart pairs in which one chart carries missing or mismatched data series, and a multimodal judge must prefer the unflawed chart. Accuracy in percent, counting a pair only when the judge picks the better chart in both presentation orders; higher is better.
Metric: Pairwise judging accuracy (%; the 164 data encoding pairs; two-pass position-swapped protocol: each of ChartJudgeBench's 1,003 human-filtered chart pairs (an original chart and a copy with one injected flaw) is judged twice with the order reversed and counts as correct only if the judge picks the better chart both times; temperature 0.1).
