Question

我有一个固定宽度和固定条形宽度的柱状图。当数据较少时，条之间的空间会增加。我想减少空间，我不介意条形图是从图表的开始还是在中间显示，但是应减小条形图的空间。一个10px的空间看起来不错。任何帮助深表感谢。这是一个演示-

Highcharts.chart('container', {
    chart: {
        type: 'column',
        width:1200
    },
    title: {
        text: 'Monthly Average Rainfall'
    },
    subtitle: {
        text: 'Source: WorldClimate.com'
    },
    xAxis: {
        categories: [
            'Jan',
            'Feb'
        ],
        crosshair: true
    },
    yAxis: {
        min: 0,
        title: {
            text: 'Rainfall (mm)'
        }
    },
    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:.1f} mm</b></td></tr>',
        footerFormat: '</table>',
        shared: true,
        useHTML: true
    },
    plotOptions: {
        column: {
            pointWidth:30
        }
    },
    series: [{
        name: 'Tokyo',
        data: [49.9, 71.5]

    }]
});

我唯一想到的就是添加一堆伪造的列，以占用额外的空间。 Highcharts似乎不像这样工作。根据{{3}}，使用pointWidth或pointPadding取决于您提供的是哪一种，但不能同时使用两者。

Highcharts.chart('container', {
    chart: {
        type: 'column',
        width:1200
    },
    title: {
        text: 'Monthly Average Rainfall'
    },
    subtitle: {
        text: 'Source: WorldClimate.com'
    },
    xAxis: {
        categories: [
            'Jan',
            'Feb',
            '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', ''
        ],
        crosshair: true
    },
    yAxis: {
        min: 0,
        title: {
            text: 'Rainfall (mm)'
        }
    },
    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:.1f} mm</b></td></tr>',
        footerFormat: '</table>',
        shared: true,
        useHTML: true
    },
    plotOptions: {
        column: {
            pointWidth: 30,
        },
    },
    series: [{
        name: 'Tokyo',
        data: [49.9, 71.5, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
    }]
});

如何在Highcharts柱形图中减小具有固定条形宽度的条形之间的间距？
