Figures and Axes

Figures and Axes

Figures and Axes (fanda) is a lightweight Python library designed to streamline the process of extracting experiment data from Weights & Biases (wandb) and generating publication-quality plots.The name is a play on "wandb" (Weights and Biases) $\rightarrow$ "fanda" (Figures and Axes).

Features

• Seamless Extraction: Pull scalar histories, configuration configs, and summary metrics from W&B runs easily.
• Publication Ready: Generate clean, professional figures using matplotlib and seaborn defaults tailored for academic papers.
• Filtering: Easily select runs based on tags, groups, or specific configuration hyperparameters.
• DataFrame Integration: Convert W&B run histories directly into Pandas DataFrames for custom analysis.

Installation

You can install fanda directly from the PyPi:

pip install fanda

Configuration

Ensure you are logged into W&B before using the library:

wandb login

Usage

Here is a simple example of how to pull data from a project and plot the training loss.

from fanda.wandb_client import fetch_wandb
from fanda import transforms
from fanda.visualizations import lineplot, add_legend, save_fig

(
    fetch_wandb("entity", "project", filters={
        "state": "finished",
        "created_at": {"$gte": "2025-01-01"},
    })
    .pipe(transforms.exponential_moving_average, column="evaluation/mean_episode_returns", alpha=0.7)
    .pipe( 
        lineplot, 
        x="_step", 
        y="loss", 
        hue="network",
        xlabel="Number of Steps",
        ylabel="Loss",
    )
    .pipe(add_legend, column="network")
    .pipe(save_fig, name="plot")
)
