ChartREG++ - Point Grounding (ChartMimic Charts): leaderboard
Chart referring-expression grounding on the ChartMimic half of ChartREG++ (Niu et al., 2026), charts drawn from scientific papers: the model must point at every chart element 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; ChartMimic half of ChartREG++; zero-shot, greedy). Source: arxiv.org. Saturation forecast: Around July 2027. 4 models tracked.
