ChartBench - Value Extraction: leaderboard
ChartBench Value Extraction (Xu et al., 2023): zero-shot yes/no questions on whether a stated data value is correct, read from legends, axes and marks rather than printed labels. Scored with Acc+, the percentage of questions where the model accepts the true assertion and rejects its paired false one, so guessing scores near zero; higher is better.
Metric: Acc+ (%). Source: chartbench.github.io. Saturation forecast: Around February 2027. 21 models tracked.
