Highcharts中的工具提示

Question

我有一个绘制柱形图的功能.我想在工具提示中添加额外的信息.

这是我的功能

function arm_bar_graph(result){

    $('#arms_graph').highcharts({
        chart: {
            type: 'column',
            backgroundColor : '#fafafa',
            height : 300,
        },
        title: {
            text: 'Load Per Arm / Open Shipments'
        },
        subtitle: {
            text: ''
        },
        xAxis: {
            categories: result[0],
            labels: {
                    rotation: -45,
                    align: 'right',
                    style: {
                        fontSize: '13px',
                        fontFamily: 'Verdana, sans-serif'
                    }
                }
        },
        yAxis: {
            min: 0,
            title: {
                text: ''
            }
        },
        tooltip: {
            headerFormat: '<span style="font-size:10px">{point.key}</span><table>',
            pointFormat: '<tr><td style="color:{series.color};padding:0">{series.name}: </td>' +
                '<td style="padding:0"><b>{point.y}</b></td></tr>',
            footerFormat: '</table>',
            shared: true,
            useHTML: true
        },
        credits: {
            enabled: false
        },
        series: [{
            data: result[1],
            name : 'Open Shipments',
        },
        ]
    });
}

结果是

我想在工具提示中添加更多信息,该工具提示包含在结果中提供的字典中.我怎样才能做到这一点？目前,工具提示显示Y轴值,即结果[1]值.

如何从字典中添加值？

Answer 1

你可以使用tooltip.formatter回调来做到这一点

ToolTip格式化程序回调代码:

tooltip: {
     formatter: function() {
          return 'The value for <b>' + this.x + '</b> is <b>' + this.y + '</b>, in series '+ this.series.name;
     }
}

参考:http://api.highcharts.com/highcharts#tooltip.formatter

在JSFIDDLE上进行演示

快乐编码:)
