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()
