SVG 作为 HighChart 堆叠柱形图中的标签

Question

我正在尝试在 highchart 中创建一个堆积柱形图，其中 x 轴标签是 SVG 图像，如下图所示：

我已经让它处理每个标签的单个数据点（即非堆叠数据），但是一旦我将输入数据更改为数组，数据就会停止呈现。 这“有效”： https://jsfiddle.net/jakobhl/krx4e5pm/2/

var dataName = function(imgSrc) {
  return '<span><img src=' + imgSrc + ' ' + 'style="width: 40px; height: 40px;"/><br></span>';
};

var data2016 = [
  [11, dataName("https://image.flaticon.com/icons/svg/197/197571.svg")],
  [11, dataName("https://image.flaticon.com/icons/svg/197/197408.svg")],
  [11, dataName("https://image.flaticon.com/icons/svg/197/197375.svg")],
  [14, dataName("https://image.flaticon.com/icons/svg/197/197374.svg")],
  [12, dataName("https://image.flaticon.com/icons/svg/197/197484.svg")],
];


Highcharts.chart('container', {
  chart: {
    type: 'column'
  },
    plotOptions: {
        column: {
            stacking: 'normal',
            dataLabels: {
                enabled: true
            }
        }
    },
  xAxis: {
    tickmarkPlacement: 'on',
    lineWidth: 0,
    type: 'category',
    labels: {
      useHTML: true,
      align: 'center'
    }
  },

  series: [{
    keys: ['y', 'name'],
    data: data2016,
  }]
});

<script src="https://code.jquery.com/jquery-3.2.1.min.js"></script>
<script src="https://code.highcharts.com/highcharts.js"></script>
<script src="https://code.highcharts.com/highcharts-more.js"></script>

<div id="container"></div>

这不会： https://jsfiddle.net/jakobhl/2rfa645x/3/

var dataName = function(imgSrc) {
  return '<span><img src=' + imgSrc + ' ' + 'style="width: 40px; height: 40px;"/><br></span>';
};

var data2016 = [
  [[11, 15], dataName("https://image.flaticon.com/icons/svg/197/197571.svg")],
  [[12, 15], dataName("https://image.flaticon.com/icons/svg/197/197408.svg")],
  [[13, 15], dataName("https://image.flaticon.com/icons/svg/197/197375.svg")],
  [[41, 15], dataName("https://image.flaticon.com/icons/svg/197/197374.svg")],
  [[11, 15], dataName("https://image.flaticon.com/icons/svg/197/197484.svg")],
];


Highcharts.chart('container', {
  chart: {
    type: 'column'
  },
    plotOptions: {
        column: {
            stacking: 'normal',
            dataLabels: {
                enabled: true
            }
        }
    },
  xAxis: {
    tickmarkPlacement: 'on',
    lineWidth: 0,
    type: 'category',
    labels: {
      useHTML: true,
      align: 'center'
    }
  },

  series: [{
    keys: ['y', 'name'],
    data: data2016,
  }]
});

<script src="https://code.jquery.com/jquery-3.2.1.min.js"></script>
<script src="https://code.highcharts.com/highcharts.js"></script>
<script src="https://code.highcharts.com/highcharts-more.js"></script>

<div id="container"></div>

如何在仍使用 SVG 作为标签的同时按国家/地区堆叠数据？

感谢 jsfiddle 用户 BlackLabel 的启发。

Answer 1

您可以添加另一个值，但您需要调整 Highcharts 所需的数据格式。如果新值为x，则如下：

var data2016 = [
    [
        11, 15, dataName("https://image.flaticon.com/icons/svg/197/197571.svg")
    ],
    ...
];


Highcharts.chart('container', {
    ...,
    series: [{
        keys: ['y', 'x', 'name'],
        data: data2016
    }]
});

我从来没有发现为什么原来的解决方案不起作用，但一个可行的解决方案是使用类别而不是系列： https://jsfiddle.net/jakobhl/L3hzeqpv/1/

var dataName = function(imgSrc) {
  return '<span><img src=' + imgSrc + ' ' + 'style="width: 40px; height: 40px;"/><br></span>';
};

Highcharts.chart('container', {
    chart: {
        type: 'column'
    },
    title: {
        text: 'Stacked column chart'
    },
    xAxis: {
        labels: {
      useHTML: true,
      align: 'center'
    },
        categories: [dataName("https://image.flaticon.com/icons/svg/197/197571.svg"), dataName("https://image.flaticon.com/icons/svg/197/197408.svg"), dataName("https://image.flaticon.com/icons/svg/197/197375.svg"), dataName("https://image.flaticon.com/icons/svg/197/197374.svg"), dataName("https://image.flaticon.com/icons/svg/197/197484.svg")]
    },
    yAxis: {
        min: 0,
        title: {
            text: 'Total fruit consumption'
        },
        stackLabels: {
            enabled: true,
            style: {
                fontWeight: 'bold',
                color: ( // theme
                    Highcharts.defaultOptions.title.style &&
                    Highcharts.defaultOptions.title.style.color
                ) || 'gray'
            }
        }
    },
    legend: {
        align: 'right',
        x: -30,
        verticalAlign: 'top',
        y: 25,
        floating: true,
        backgroundColor:
            Highcharts.defaultOptions.legend.backgroundColor || 'white',
        borderColor: '#CCC',
        borderWidth: 1,
        shadow: false
    },
    tooltip: {
        headerFormat: '<b>{point.x}</b><br/>',
        pointFormat: '{series.name}: {point.y}<br/>Total: {point.stackTotal}'
    },
    plotOptions: {
        column: {
            stacking: 'normal',
            dataLabels: {
                enabled: true
            }
        }
    },
    series: [{
        name: 'John',
        data: [5, 3, 4, 7, 2]
    }, {
        name: 'Jane',
        data: [2, 2, 3, 2, 1]
    }, {
        name: 'Joe',
        data: [3, 4, 4, 2, 5]
    }]
});
