matplotlib-jp-diagram

This skill provides a standard way to generate matplotlib diagrams with Japanese font support and consistent output naming.

Guidelines

1. Mandatory Font Configuration: Always include the following line before plotting:

``python import matplotlib.pyplot as plt plt.rcParams['font.family'] = 'Noto Sans JP' ``

1. File Naming Convention:

- The Python script should be named with a suffix like -diagram.py (e.g., performance-diagram.py). - The output image must be a PNG file with the exact same base name (e.g., performance-diagram.png).

1. Output Logic:

Ensure the script automatically saves the diagram to the correct PNG path when executed.

``python import os outputpath = os.path.splitext(os.path.basename(file))[0] + ".png" plt.savefig(outputpath) ``

1. Appropriate Diagrams:

- Choose the chart type (line, bar, scatter, etc.) that best represents the data. - Include appropriate labels, titles, and legends in Japanese where applicable.

Workflow

1. Identify the data to be visualized.
2. Determine the script name (e.g., stats-diagram.py).
3. Generate the script using the template logic.
4. If requested, execute the script to verify output.
