Two main tools for Python academic visualization

Python academic visualization primarily uses Matplotlib (low-level) and Seaborn (high-level statistical plotting built on Matplotlib). Matplotlib offers high flexibility for complex custom figures; Seaborn provides concise syntax with built-in statistical charts and attractive color schemes.

Matplotlibrc configuration and publication-grade style settings

• [Method 1: matplotlibrc file (permanent)] font.family: serif font.serif: Times New Roman figure.dpi: 300 savefig.dpi: 300
• [Method 2: Python code (recommended for scripts)] import matplotlib.pyplot as plt plt.rcParams['font.family'] = 'Times New Roman' plt.rcParams['font.size'] = 10 plt.rcParams['figure.dpi'] = 300

Seaborn publication color schemes

• [Recommended academic palettes] colors = ['#1f77b4', '#ff7f0e', '#2ca02c', '#d62728', '#9467bd']
• [Grayscale-friendly palette] gray_colors = ['#000000', '#404040', '#808080', '#BFBFBF']
• [Continuous gradients] sns.color_palette("Blues", as_cmap=True) sns.color_palette("RdBu_r", as_cmap=True)

Code templates for various academic charts

• [Error bar plot] plt.errorbar(x, y, yerr=yerr, fmt='o', capsize=3, markersize=4, linewidth=1.5)
• [Correlation heatmap] sns.heatmap(corr, cmap='RdBu_r', center=0, annot=True)
• [Multi-subplot] fig, axes = plt.subplots(2, 2)

Matplotlib-LaTeX integration

• [Enable LaTeX rendering] plt.rcParams['text.usetex'] = True
• [Math symbols without full LaTeX] plt.rcParams['text.usetex'] = False plt.xlabel(r'$\alpha + \beta = \gamma )

Export formats and resolution standards

• [Vector formats (preferred)] plt.savefig('figure1.pdf', bbox_inches='tight') plt.savefig('figure1.svg', bbox_inches='tight')
• [Bitmap formats] plt.savefig('figure1.tiff', dpi=300, bbox_inches='tight')

Frequently asked questions

Matplotlib or Seaborn for academic plotting?

Seaborn for quick statistical charts; Matplotlib for fine-grained custom figures. In practice: use Seaborn for rapid exploration, then refine with Matplotlib.

Chinese characters showing as boxes in Matplotlib?

Matplotlib does not support Chinese by default. Solution: download and install Chinese font TTF files, place in matplotlib font directory, delete font cache, set plt.rcParams['font.sans-serif'] = ['SimHei'].

How to export figures for journal submission?

Vector formats first (PDF/SVG/EPS) — infinitely scalable. If bitmap required, use TIFF or PNG at 300 DPI.
