javascript - Highcharts - 气泡图 - 移动网格线

Question

我创建了一个 highcharts 气泡图，如下所示:

jsFiddle

如果可能的话，我希望 a 轴网格线位于气泡的中间。

有没有办法实现这个？

代码如下:

$(function () {

    var data = [{ x: 0, y: 1, z: 1, dataSeries: 'data #1', dataPerc: '1.2' },
                { x: 1, y: 2, z: 2, dataSeries: 'data #2', dataPerc: '2.2' },
                { x: 2, y: 0, z: 0, dataSeries: 'data #3', dataPerc: '19.2' },
                { x: 3, y: 7, z: 7, dataSeries: 'data #4', dataPerc: '12.0' },
                { x: 4, y: 5, z: 5, dataSeries: 'data #5', dataPerc: '24' },
                { x: 5, y: 4, z: 4, dataSeries: 'data #6', dataPerc: '12' },
                { x: 6, y: 3, z: 3, dataSeries: 'data #7', dataPerc: '15.3' },
                { x: 7, y: 3, z: 3, dataSeries: 'data #8', dataPerc: '1.2' }];         

    $('#container').highcharts({

        chart: {
            type: 'bubble',
            plotBorderWidth: 1,
            zoomType: 'xy'
        },
            credits: false,

        legend: {
            enabled: false
        },

        title: {
            text: ''
        },

        xAxis: {
            gridLineWidth: 1,
            title: {
                text: ''
            },
           categories: ['data #1', 'data #2', 'data #3', 'data #4', 'data #5', 'data #6', 'data#7', 'data #8']
        },

        yAxis: {
            startOnTick: true,
            min: 0,
            max: 7,
            title: {
                text: 'Score'
            },
            labels: {
                format: '{value}'
            },
            maxPadding: 0.2
        },

        tooltip: {
            useHTML: true,
            headerFormat: '<table>',
            pointFormat: '<tr><th colspan="2"><h3>{point.dataSeries}</h3></th></tr>' +
                '<tr><th>Score:</th><td>{point.y}</td></tr>' +
                '<tr><th>Percentage:</th><td>{point.dataPerc}%</td></tr>',
            footerFormat: '</table>',
            followPointer: true
        },

        plotOptions: {
            series: {
                dataLabels: {
                    enabled: true,
                    format: '{point.name}'
                }
            }
        },
        series: [{ data: data }]
    });
});

Answer 1

您可以使用 tickmarkPlacement option :

xAxis: {
    tickmarkPlacement: 'on'
}

For categorized axes only. If on the tick mark is placed in the center of the category, if between the tick mark is placed between categories. The default is between if the tickInterval is 1, else on. Defaults to null.
