Highcharts。如何从Y轴开始绘制区域图？

Question

我是一个新手，所以我可能错过了一些东西。最近我在做区域图，我能够绘制图表，一切都很完美，但我有一个要求，我有区域图应该从x轴开始作为0。我已经附上了一张截图和fiddle链接.这里是fiddle链接。https:/jsfiddle.netshantanugade9vwxm412

Highcharts.chart('container', {
chart: {
    type: 'area'
},

title: {
    text: 'US and USSR nuclear stockpiles'
},
xAxis: {
    allowDecimals: false,
    labels: {
        formatter: function () {
            return this.value; // clean, unformatted number for year
        }
    },
    accessibility: {
        rangeDescription: 'Range: 1940 to 2017.'
    }
},
yAxis: {
    title: {
        text: 'Nuclear weapon states'
    },
    labels: {
        formatter: function () {
            return this.value / 1000 + 'k';
        }
    }
},
tooltip: {
    pointFormat: '{series.name} had stockpiled <b>{point.y:,.0f}</b><br/>warheads in {point.x}'
},
plotOptions: {
    area: {
        pointStart: 1940,
        marker: {
            enabled: false,
            symbol: 'circle',
            radius: 2,
            states: {
                hover: {
                    enabled: true
                }
            }
        }
    }
},
series: [{

    data: [
        null, null, null, null, null, 6, 11, 32, 110, 235,

        5113, 5113, 4954, 4804, 4761, 4717, 4368, 4018
    ]

    name: 'USSR/Russia',
    data: [ 1605, 2471, 3322, 4238, 5221, 6129, 7089, 8339, 9399, 10538,

        1605, 2471, 3322, 4238, 5221, 6129, 7089, 8339, 9399, 10538,

        30062, 32049, 33952, 35804, 37431, 39197, 45000, 43000, 41000, 39000,
        37000, 35000, 33000, 31000, 29000, 27000, 25000, 24000, 23000, 22000,
        21000, 20000, 19000, 18000, 18000, 17000, 16000, 15537, 14162, 12787,
        12600, 11400, 5500, 4512, 4502, 4502, 4500, 4500
    ]
}] })

正如你可以看到在图像中有一个小的差距。

Answer 1

你需要减少 xAxis.minPadding 财产。

    xAxis: {
        minPadding: 0,
        ...
    }
