## About CharXiv (overall)

- Year: 2024
- Tasks: Scientific chart description and reasoning
- Format: Chart understanding and reasoning
- Difficulty: Scientific visualization reasoning

BenchLM keeps the combined descriptive-plus-reasoning score on its own display-only key because the descriptive split is markedly easier than the reasoning split. Mixing a combined score into the weighted CharXiv reasoning lane would overstate chart reasoning.

CharXiv (overall) is currently displayed on BenchLM for reference, but it is excluded from the weighted scoring formula.
