How to submit charts and other additional materials to the journal?

Journal submission portals universally support digital uploads of supplementary materials like charts, datasets, or multimedia during the manuscript submission process. These files accompany the main manuscript but are often submitted separately. Specific format requirements (e.g., TIFF, EPS, PDF), resolution (minimum 300 DPI for images), and labeling conventions vary significantly by journal. Consult the journal's "Author Guidelines" meticulously, particularly the sections on "Figures," "Supplementary Information," or "Data Availability." Ensure each figure/chart is clearly numbered, has a concise caption, and is referenced appropriately within the main manuscript text. Data underlying charts must also adhere to stated policies. To implement this, identify the designated supplementary materials section within the online submission system after uploading your manuscript. Use this area to upload all non-core files, strictly following the journal's specifications for acceptable formats, file sizes, and naming. Clearly label each file and double-check their visibility and accessibility after submission to prevent handling delays.
