如何从x轴的特定点添加动态y轴。

suppose my x-axis values are (jan,feb,march....dec)

i want to generate y axis from Jun-dec (x-axis)。

当我点击按钮但它生成 yaxis 并从x轴开始 jan-july 而不是 jun-dec

请参阅jsfiddle，您可以清楚地了解我的问题。

var chart = Highcharts.chart('container', {

    xAxis: {
        categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
    },

    yAxis: {
        title: {
            text: 'Temperature'
        },
        lineWidth: 2,
        lineColor: '#F33',
        id: 'temperature-axis'
    },

    series: [{
        name: 'Temperature',
        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],
        color: '#F33'
    }]
});

// the button handlera
$('#add').click(function () {
    chart.addAxis({ // Secondary yAxis
        id: 'rainfall-axis',
        title: {
            text: 'Rainfall'
        },
        lineWidth: 2,
        lineColor: '#08F',
        opposite: true
    });
    chart.addSeries({
        name: 'Rainfall',
        type: 'line',
        color: '#08F',
        yAxis: 'rainfall-axis',
        data: [135.6, 148.5, 216.4, 194.1, 95.6, 54.4]
    });
     $(this).attr('disabled', true);
 });

上述问题可以通过

解决

1＆GT;使用null值更新数组以匹配xAxis类别

$('#add').click(function () {
    chart.addAxis({ // Secondary yAxis
        id: 'rainfall-axis',
        title: {
            text: 'Rainfall'
        },
        lineWidth: 2,
        lineColor: '#08F',
        opposite: true
    });
    chart.addSeries({
        name: 'Rainfall',
        type: 'line',
        color: '#08F',
        yAxis: 'rainfall-axis',
        data: [null,null,null,null,null,null,135.6, 148.5, 216.4, 194.1, 95.6, 54.4]  //update with null values
    });
    $(this).attr('disabled', true);
 });

2 - ;使用pointStart从要开始的值传递额外参数。

$('#add').click(function () {
    chart.addAxis({ // Secondary yAxis
        id: 'rainfall-axis',
        title: {
            text: 'Rainfall'
        },
        lineWidth: 2,
        lineColor: '#08F',
        opposite: true
    });
    chart.addSeries({
        name: 'Rainfall',
        type: 'line',
        color: '#08F',
        yAxis: 'rainfall-axis',
        pointStart: 6, //start point
        data: [135.6, 148.5, 216.4, 194.1, 95.6, 54.4]
    });
    $(this).attr('disabled', true);
 });

Answer 2

您必须将null添加到数据集

data: [null,null,null,null,null,null,135.6, 148.5, 216.4, 194.1, 95.6, 54.4]
