javascript - 通过绘图 API 渲染 Highcharts 数据表以将容器分隔为图表？

Question

根据 HighCharts 文档，我正在研究此处给出的示例，以便能够添加和呈现数据表:

“我可以在导出的图表中添加数据表吗？”

是的，在 Highcharts 数据和绘图 API 上进行一些编程，您就可以绘制表格。参见 http://jsfiddle.net/highcharts/z9zXM/源代码和实例。”

我正在尝试弄清楚如何将数据表呈现到与图表不同的容器中。感谢您的帮助。

来自 JS Fiddle:

/**
 * Create the data table
 */
Highcharts.drawTable = function() {

    // user options
    var tableTop = 310,
        colWidth = 100,
        tableLeft = 20,
        rowHeight = 20,
        cellPadding = 2.5,
        valueDecimals = 1,
        valueSuffix = ' °C';

    // internal variables
    var chart = this,
        series = chart.series,
        renderer = chart.renderer,
        cellLeft = tableLeft;

    // draw category labels
    $.each(chart.xAxis[0].categories, function(i, name) {
        renderer.text(
            name, 
            cellLeft + cellPadding, 
            tableTop + (i + 2) * rowHeight - cellPadding
        )
        .css({
            fontWeight: 'bold'
        })       
        .add();
    });

    $.each(series, function(i, serie) {

            // horizontal lines
            if (row == 0) {
                Highcharts.tableLine( // top

我想你想在不同的容器中呈现表格。因此，为此您可以在示例中使用相同代码的两个容器中使用图表。唯一的区别是您必须在第二个容器中隐藏图表并加载表函数。

 window.chart = new Highcharts.Chart({
    chart: {
        renderTo: 'container2',
        events: {
            load: Highcharts.drawTable,
        },
        borderWidth: 2
    },
     title: {
        text: ''
    },
    
    xAxis: {
        categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'],
        visible:false
    },
    
    yAxis: {
        title: {
            text: 'Temperature (°C)'
        },
        visible:false
    },

    legend: {
       enabled:false
    },

   series: [{
         name: 'Tokyo',
         data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6],
         visible:false
      }, {
         name: 'New York',
         data: [-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5],
         visible:false
      }, {
         name: 'Berlin',
         data: [-0.9, 0.6, 3.5, 8.4, 13.5, 17.0, 18.6, 17.9, 14.3, 9.0, 3.9, 1.0],
         visible:false
      }, {
         name: 'London',
         data: [3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8],
         visible:false
      }]
    })
window.chart = new Highcharts.Chart({

    chart: {
        renderTo: 'container',
        events: {
            //load: Highcharts.drawTable
        },
        borderWidth: 2
    },
    
    title: {
        text: 'Average monthly temperatures'
    },
    
    xAxis: {
        categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
    },
    
    yAxis: {
        title: {
            text: 'Temperature (°C)'
        }
    },

    legend: {
        //y: -300
    },

    series: [{
         name: 'Tokyo',
         data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6]
      }, {
         name: 'New York',
         data: [-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5]
      }, {
         name: 'Berlin',
         data: [-0.9, 0.6, 3.5, 8.4, 13.5, 17.0, 18.6, 17.9, 14.3, 9.0, 3.9, 1.0]
      }, {
         name: 'London',
         data: [3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8]
      }]
});
