Supertree是一个用于构建和可视化系统发生树的Python库,特别适合生物分类学中的应用。它的核心功能包括树的构建、分支长度调整和绘制美观的树形图。如果你想要在使用Supertree时自定义绘图样式,通常需要利用其提供的API结合Matplotlib或其他绘图库。
以下是一些基本步骤来自定义Supertree的绘图:
1. 导入必要的模块:
```python
import supertree
import matplotlib.pyplot as plt
```
2. 创建SuperTree实例并构建树:
```python
model = ... # 你的模型对象
tree_data = ... # 树的数据结构
super_tree = supertree.SuperTree(model, tree_data)
```
3. 调用绘图函数,并传递自定义参数:
```python
fig, ax = plt.subplots(figsize=(width, height))
# supertree.plot() 或者 specific method like super_tree.plot(ax=ax, **kwargs)
# 其中kwargs可能包含如color_map, edge_color, node_size等属性来自定义颜色、边线和节点大小
```
示例:
```python
custom_colors = {'group1': 'blue', 'group2': 'red'}
super_tree.plot(node_colors=custom_colors, ax=ax)
```
4. 自定义额外样式,如调整字体大小、添加标签等:
```python
for n in super_tree.treenode_iter():
n.name_fontsize = 10
```
5. 显示或保存图表:
```python
plt.show() # 显示
plt.savefig('my_custom_tree.png') # 保存到文件
```
