ChartREG++ - Point Grounding (ECDBench Charts): leaderboard
Chart referring-expression grounding on the ECDBench half of ChartREG++ (Niu et al., 2026): the model must point at every chart element (bars, markers, lines, legend parts and more) that an expression refers to through textual, data or visual clues, often several targets per expression. Macro F1 in percent after one-to-one Hungarian matching, a point matching when it falls inside the element mask or within 5 pixels of it; zero-shot, higher is better.
Metric: Macro F1 (%; predicted points matched one-to-one to the referred chart elements by Hungarian matching, a point matching when it falls inside the element's mask or within 5 px of it; ECDBench half of ChartREG++; zero-shot, greedy). Source: arxiv.org. Saturation forecast: Around October 2027. 4 models tracked.
