一、适用条件
1、桑基图：用于查看用户的行为,需要对产品流程有所了解,比如客户的引导与流失,这里画一个比较简单的,也是官网的例子。
二、代码实现
1.导入所需包
from pyecharts import options as opts
from pyecharts.charts import Sankey
from pyecharts.render import make_snapshot
#from snapshot_phantomjs import snapshot
from snapshot_pyppeteer import snapshot
2.数据整理
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},
]
3 .桑基图
def Sankey_chart() -> Sankey:
################## 这部分可以直接用，保存成网页
c= (
Sankey(init_opts=opts.InitOpts(width="1000px", height="500px"))
.add(
series_name="",
nodes=nodes,
links=links,
itemstyle_opts=opts.ItemStyleOpts(border_width=1, border_color="#aaa"),
linestyle_opt=opts.LineStyleOpts(color="source", curve=0.5, opacity=0.5),
tooltip_opts=opts.TooltipOpts(trigger_on="mousemove"),
)
.set_global_opts(title_opts=opts.TitleOpts(title="Sankey Diagram"))
# .render("1.html")
)
####################
return c
make_snapshot(snapshot, Sankey_chart().render(), "13_1.gif")
if __name__ == '__main__':
Sankey_chart()
