小白学Python（15）——pyecharts 绘制树形图表 Tree

Tree-基本示例

import json
import os

from pyecharts import options as opts
from pyecharts.charts import Page, Tree

data = [
        {
            "children": [
                {"name": "B"},
                {
                    "children": [
                        {"children": [{"name": "I"}], "name": "E"},
                        {"name": "F"},
                    ],
                    "name": "C",
                },
                {
                    "children": [
                        {"children": [{"name": "J"}, {"name": "K"}], "name": "G"},
                        {"name": "H"},
                    ],
                    "name": "D",
                },
            ],
            "name": "A",
        }
    ]

tree=(
     Tree()
        .add("", data)
        .set_global_opts(title_opts=opts.TitleOpts(title="Tree-基本示例"))
    )

tree.render()

import json
import os

from pyecharts import options as opts
from pyecharts.charts import Page, Tree
        
data = [
        {
            "children": [
                {"name": "B"},
                {
                    "children": [
                        {"children": [{"name": "I"}], "name": "E"},
                        {"name": "F"},
                    ],
                    "name": "C",
                },
                {
                    "children": [
                        {"children": [{"name": "J"}, {"name": "K"}], "name": "G"},
                        {"name": "H"},
                    ],
                    "name": "D",
                },
            ],
            "name": "A",
        }
    ]


        
tree=(
     Tree()
        .add("", data,orient="RL")
        .set_global_opts(title_opts=opts.TitleOpts(title="Tree-左右方向"))
    )
tree.render()

更改orient="TB"/"BT"分别为上下，下上

Tree-Layout

import json
import os

from pyecharts import options as opts
from pyecharts.charts import Page, Tree
        
data = [
        {
            "children": [
                {"name": "B"},
                {
                    "children": [
                        {"children": [{"name": "I"}], "name": "E"},
                        {"name": "F"},
                    ],
                    "name": "C",
                },
                {
                    "children": [
                        {"children": [{"name": "J"}, {"name": "K"}], "name": "G"},
                        {"name": "H"},
                    ],
                    "name": "D",
                },
            ],
            "name": "A",
        }
    ]
        
tree=(
     Tree()
        .add("",data,collapse_interval=2, layout="radial")
        .set_global_opts(title_opts=opts.TitleOpts(title="Tree-Layout"))
    )
tree.render()

TreeMap-基本示例

import json
import os

from pyecharts import options as opts
from pyecharts.charts import Page, TreeMap

data = [
        {"value": 40, "name": "我是A"},
        {
            "value": 180,
            "name": "我是B",
            "children": [
                {
                    "value": 76,
                    "name": "我是B.children",
                    "children": [
                        {"value": 12, "name": "我是B.children.a"},
                        {"value": 28, "name": "我是B.children.b"},
                        {"value": 20, "name": "我是B.children.c"},
                        {"value": 16, "name": "我是B.children.d"},
                    ],
                }
            ],
        },
    ]

treemap = (
        TreeMap()
        .add("演示数据", data)
        .set_global_opts(title_opts=opts.TitleOpts(title="TreeMap-基本示例"))
    )


treemap.render()
