這篇文章主要介紹了Python可視化神器pyecharts繪制?；鶊D，即?；芰糠至鲌D，也叫?；芰科胶鈭D，更多相關(guān)介紹具有一定的參考價值，需要的朋友可以參考一下

桑基圖

?；鶊D（Sankey diagram），即桑基能量分流圖，也叫桑基能量平衡圖。它是一種特定類型的流程圖，圖中延伸的分支的寬度對應(yīng)數(shù)據(jù)流量的大小，通常應(yīng)用于? ?能源???、材料成分、? ?金融 ???等數(shù)據(jù)的可視化分析。因1898年Matthew Henry Phineas Riall Sankey繪制的“? ?蒸汽機 ??的能源效率圖”而聞名，此后便以其名字命名為“?；鶊D”。

?；鶊D最明顯的特征就是，始末端的分支寬度總和相等，即所有主支寬度的總和應(yīng)與所有分出去的分支寬度的總和相等，保持能量的平衡。

第一個?；鶊D

from pyecharts import options as opts
from pyecharts.charts import Sankey

nodes = [
{"name": "category1"},
{"name": "category2"},
{"name": "category3"},
{"name": "category4"},
{"name": "category5"},
{"name": "category6"},
]

links = [
{"source": "category1", "target": "category2", "value": 10},
{"source": "category2", "target": "category3", "value": 15},
{"source": "category3", "target": "category4", "value": 20},
{"source": "category5", "target": "category6", "value": 25},
]
c = (
Sankey()
.add(
"sankey",
nodes,
links,
linestyle_opt=opts.LineStyleOpts(opacity=0.2, curve=0.5, color="source"),
label_opts=opts.LabelOpts(position="right"),
)
.set_global_opts(title_opts=opts.TitleOpts(title="標(biāo)題"))
