bland-altman 0.1.4

Lightweight Bland–Altman plot implementation for method comparison

Bland-Altman Plot

A lightweight Python library for generating Bland-Altman Plots to evaluate agreement between two measurements methods. This implementation provides a simple interface for quickly visualizing bias and limits of agreements.

Installation

Install from PyPI

pip install bland-altman

Usage

import numpy as np
from bland_altman import bland_altman_plot

# Generate example data
np.random.seed(42) 
x = np.random.normal(100,10,500)
y = x + np.random.normal(0,5,500)

# Generate Bland-Altman plot
bland_altman_plot(x, y, ylim=(-20, 20), figsize=(10,6), label_offset=0.025, color='blue', alpha=0.5, display_grid=True, display_legend=True)
