Researchers have developed new benchmarks and methods to improve the reasoning capabilities of multimodal large language models (MLLMs) when analyzing complex charts. The LongChart VQA benchmark introduces a dataset with an average of 6.5 images and 31.2 questions per set, designed to test MLLMs on multi-chart understanding and inference. Additionally, a new approach called Chart Specification uses structural representations to guide VLM reasoning for chart-to-code generation, showing significant improvements in fidelity and data efficiency.
