介绍 / Introduction

A Python reproduction of the MATLAB special heatmap project. It uses matplotlib to draw advanced heatmaps with various shapes (square, circle, hexagon, pie, etc.) and triangular layouts.

基于 MATLAB 版 special heatmap 的 Python 复现。本项目使用 matplotlib 实现具有多种形状（正方形、圆形、六边形、饼图等）和三角矩阵布局的高级热图绘制。

1. 安装 / Installation

pip install special-heatmap

2. 基础使用 / Basic Use

2.1 绘制非负矩阵热图 (Draw positive heat map)

import numpy as np
import matplotlib.pyplot as plt
from special_heatmap import SHeatmap

data = np.random.rand(15, 15)
shm = SHeatmap(data, fmt='sq')
shm.draw()
plt.show()

2.2 绘制含负数热图 (Contains negative numbers)

data = np.random.rand(15, 15) - 0.5
shm = SHeatmap(data, fmt='sq')
shm.draw()
plt.show()

2.3 绘制有文本和 NaN 的热图 (Draw heat map with texts and NaN)

data = np.random.rand(12, 12) - 0.5
data[3, 3] = np.nan
shm = SHeatmap(data, fmt='sq')
shm.draw()
shm.set_text(fontsize=8)
plt.show()

3. 各类型热图 / Various Formats

支持的格式 (fmt 参数): sq (Default), pie, circ, oval, hex, asq, acirc.

# 示例：绘制饼图格式
shm = SHeatmap(data, fmt='pie')
shm.draw()

Format	Positive Data (A)	Mixed Data (B)
sq (Square)
pie (Pie Chart)
circ (Circle)
hex (Hexagon)
oval (Oval)
asq (Auto-Square)
acirc (Auto-Circle)

4. 三角布局 / Triangular Layouts

支持以下布局类型 (set_type 方法):

• triu : 上三角 (Upper Triangle)
• tril : 下三角 (Lower Triangle)
• triu0 : 上三角无对角线 (Upper without Diagonal)
• tril0 : 下三角无对角线 (Lower without Diagonal)

data = np.random.rand(12, 12)
shm = SHeatmap(data, fmt='sq')
shm.set_type('tril') # 设置为下三角
shm.draw()
shm.set_text()
plt.show()

Type	Result
triu
tril
triu0
tril0
