高级图表三键图，系列颜色

Question

如何使系列颜色与数据颜色相同？

在这个例子中，“不平衡”数据是红色的，但是序列是蓝色的。

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'
    }]

});

更新理解。使用节点是必要的。https://jsfiddle.net/p4f21w7e/

关键是要认识到有两种方法可以为你的图表着色：

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

看一下这个例子：

 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}
    ]
}]

节点按照呈现的顺序(从左到右，向下移动)使用系列颜色着色。所以，在这个例子中：

• “红色”优先(使用series[].colors)
• 然后是“彩色演示”(它使用series[].colors1)
• 回到格林(series[].colors2)
• 下降到“蓝色”(使用series[].colors3)
• 然后转到橘子(series[].colors4)
• 最后是黄色(series[].colors5)

流本身是按照该数据点的关联颜色着色的，因此这是一个直接的向前关联。

您可以使用sankey系列类型的“颜色”属性。

https://api.highcharts.com/highcharts/series.sankey.colors

series: [{
    keys: ['from', 'to', 'weight'],
    data: [
        {from:'Brazil', to:'Portugal', weight:5},
        ['Canada', 'Portugal', 1 ],
        ['Canada', 'France', 5 ],
        ['Canada', 'England', 1 ],
        ['Mexico', 'Portugal', 1 ],
        ['Mexico', 'France', 1 ],
        ['Mexico', 'Spain', 5 ],
        ['Mexico', 'England', 1 ],
        ['USA', 'Portugal', 1 ],
        ['USA', 'France', 1 ],
        ['USA', 'Spain', 1 ],
        ['USA', 'England', 5 ]
    ],
    type: 'sankey',
    name: 'Sankey demo series',
    colors: ['#00796B', '#ff0000', '#00ff00','#0000ff']
}]
