How to provide charts and additional materials when submitting to a journal?

When submitting manuscripts to academic journals, including charts and supplementary materials is essential and typically facilitated through specific journal submission systems. Adherence to the target journal's detailed Author Guidelines is mandatory for successful inclusion. These guidelines specify permitted file formats (e.g., TIFF, EPS for figures; PDF, Excel, ZIP for supplements), required resolutions for images, preferred citation styles within captions, and instructions for numbering/labeling. Ensure all figures are cited in the main text and that permissions are secured for copyrighted material. Supplementary files must be essential, relevant, and clearly described, avoiding redundancy with the main text. Complete metadata (e.g., legends, descriptions) is crucial. First, identify and thoroughly review the journal's specific author instructions regarding figures and supplementary data. Prepare your charts according to their stipulated technical requirements (resolution, format, size, color mode). Compile supplementary materials into designated file formats. Upload each figure and supplementary file individually through the manuscript submission portal, providing accurate, detailed captions or descriptions. Finally, verify all materials display correctly in the system's preview before final submission.
