javascript - Highcharts 桑基图，系列颜色

Question

如何使系列颜色与数据颜色相同？

在示例中，“不平衡”数据为红色，但该系列为蓝色。

Highcharts.chart('container', {

    title: {
        text: 'Highcharts Sankey Diagram'
    },

    series: [{
            colors: ["#90CAF9", "#F44336", "#1565C0"],
        keys: ['from', 'to', 'weight'],
        data: [
            {name: "prop-1", color: "#90CAF9", from: "prop-1", to: "transition", weight: 0},
            {name: "prop-2", color: "#90CAF9", from: "prop-2", to: "transition", weight: 4.14},             
            {name: "imbalance", color: "#F44336", from: "imbalance", to: "transition", weight: 0.6},
            {name: "prop-3", color: "#1565C0", from: "transition", to: "prop-3", weight: 4.74},
            {name: "prop-4", color: "#1565C0", from: "transition", to: "prop-4", weight: 0},
        ],
        type: 'sankey',
        name: 'Sankey demo series'
    }]

});

更新明白了。有必要使用节点。 https://jsfiddle.net/p4f21w7e/

要认识到的关键是，有两种方法可以为图表着色:

• 系列颜色 (series[].colors) 将为节点着色。
• 系列数据 (series[].data[].color) 为您的流程着色。

看看这个例子:

 series: [{
    colors: ["#880000",  "#AFAFAF",  "#008800", "#000088", "#ffb238", "#ffee37"],
    data: [

        {color: "#BB0000", from: "Red", to: "Colour Demo", weight: 10},
        {color: "#00BB00", from: "Green", to: "Colour Demo", weight: 4},                       {color: "#0000BB",  from: "Blue", to: "Colour Demo", weight: 6},
        {color: "#ffb238", from: "Colour Demo", to: "Orange", weight: 10},
        {color: "#ffee37",  from: "Colour Demo", to: "Yellow", weight: 10}
    ]
}]

节点按照渲染顺序(从左到右，向下移动)使用系列颜色进行着色。所以，在这个例子中:

• 首先是“红色”(使用 series[].colors[0])
• 然后是“颜色演示”(使用 series[].colors[1])
• 回到绿色 (series[].colors[2])
• 下降到“蓝色”(使用 series[].colors[3])
• 然后转到橙色 (series[].colors[4])
• 最后是黄色 (series[].colors[5])

流本身根据该数据点的关联颜色进行着色，因此这是一个直接的关联。
