Sankey Diagram高度表问题

Question

我想生成一个像下面这样的Sankey Diagram，到目前为止，我使用的数据是这样的系列：

 keys: ['from', 'to' ,'weight'],
        data: [
        ['Entrance  A', 'Platform 1' , 10 ],
        ['Entrance  A', 'Platform 2' , 2 ],
        ['Entrance B', 'Platform 2' , 3 ],
        ['Entrance C', 'Platform 3' , 5 ],
        ['Entrance D', 'Platform 4' , 7 ],
        ['Entrance E', 'Platform 1' , 6 ],
        ['Entrance F', 'Platform 2' , 10 ],
        ['Entrance F', 'Platform 4' , 4 ],
        ['Entrance G', 'Platform 1' , 13 ],
        ['Platform 1', 'Exit F' , 9 ],
        ['Platform 2', 'Exit D' , 10 ],
        ['Platform 2', 'Exit F' , 4 ],
        ['Platform 3', 'Exit G' , 5 ],
        ['Platform 3', 'Exit B' , 11 ],
        ['Platform 4', 'Exit C' , 5 ],
        ['Platform 4', 'Exit E' , 6]
        ]

但这会生成三个节点图

​

我应该使用什么类型的数据来获得与图1中给出的类似类型的图形

Answer 1

对于平台，您可以创建两种类型的节点：'Platform X from‘和'Platform X to’。然后，可以使用nodes部分重新定义它们，使它们具有相同的名称和相同的颜色：

series: [{
    type: 'sankey',
    keys: ['from', 'to' ,'weight'],
    data: [
        ['Entrance A', 'Platform 1 to' , 10 ],
        ['Entrance A', 'Platform 2 to' , 2 ],
        ['Entrance B', 'Platform 2 to' , 3 ],
        ['Entrance C', 'Platform 3 to' , 5 ],
        ['Entrance D', 'Platform 4 to' , 7 ],
        ['Entrance E', 'Platform 1 to' , 6 ],
        ['Entrance F', 'Platform 2 to' , 10 ],
        ['Entrance F', 'Platform 4 to' , 4 ],
        ['Entrance G', 'Platform 1 to' , 13 ],
        ['Platform 1 from', 'Exit F' , 9 ],
        ['Platform 2 from', 'Exit D' , 10 ],
        ['Platform 2 from', 'Exit F' , 4 ],
        ['Platform 3 from', 'Exit G' , 5 ],
        ['Platform 3 from', 'Exit B' , 11 ],
        ['Platform 4 from', 'Exit C' , 5 ],
        ['Platform 4 from', 'Exit E' , 6]
    ],
    nodes: [
        {id: 'Platform 1 from', 'name': 'Platform 1', colorIndex: 0},
        {id: 'Platform 1 to',   'name': 'Platform 1', colorIndex: 0},

        {id: 'Platform 2 from', 'name': 'Platform 2', colorIndex: 1},
        {id: 'Platform 2 to',   'name': 'Platform 2', colorIndex: 1},

        {id: 'Platform 3 from', 'name': 'Platform 3', colorIndex: 2},
        {id: 'Platform 3 to',   'name': 'Platform 3', colorIndex: 2},

        {id: 'Platform 4 from', 'name': 'Platform 4', colorIndex: 3},
        {id: 'Platform 4 to',   'name': 'Platform 4', colorIndex: 3},
    ]
}]
