Question 1

Why do Matlab default plots look unprofessional?

Accepted Answer

Matlab defaults are for general display, not academic publication. Main issues: fonts too small (8pt should be 10-12pt), lines too thin (0.5pt should be 1.5-2pt), colors too saturated, tick marks facing inward by default.

Question 2

What line width should academic figures use?

Accepted Answer

Academic figures typically use 1-2pt line widths. Lines under 1pt become invisible when printed or scaled down; lines over 2.5pt obscure data details.

Question 3

What format is best for journal submission?

Accepted Answer

EPS vector format first: infinitely scalable, clearest quality. If bitmap required, use TIFF 300 DPI or PNG 300 DPI. Avoid JPEG (compression artifacts) and BMP (too large).
