本篇內(nèi)容主要講解“Python怎么使用pyecharts繪制?;鶊D”,感興趣的朋友不妨來(lái)看看。本文介紹的方法操作簡(jiǎn)單快捷,實(shí)用性強(qiáng)。下面就讓小編來(lái)帶大家學(xué)習(xí)“Python怎么使用pyecharts繪制?;鶊D”吧!
?;鶊D(Sankey diagram),即?;芰糠至鲌D,也叫?;芰科胶鈭D。它是一種特定類型的流程圖,圖中延伸的分支的寬度對(duì)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(jī)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。
