javascript - 带有彩色backgroundcolumns的Highcharts

是否有可能获得如图所示的图表。主要目标是为每个时间单位赋予不同的背景色，例如为图表中的每一天赋予一种颜色...。

最佳答案

使用xAxis.plotbands完成垂直背景色（或对于垂直方向使用yAxis.plotbands），如下所示：

xAxis: {
    plotBands: [
        {
            from: ${x1},
            to: ${x2},
            color: ${color}
        },
    ],
    // more configuration...
}

$(function () {
    $('#container').highcharts({
        title: {
            text: 'Monthly Average Temperature',
        },
        subtitle: {
            text: 'Source: WorldClimate.com',
        },
        xAxis: {
            type: 'linear',
            tickPositions: [ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 ],
            plotBands: [
                { from: 1, to: 2, color: 'rgba(127, 255, 127, 0.5)' },
                { from: 2, to: 3, color: 'rgba(255, 255, 63, 0.5)' },
                { from: 3, to: 4, color: 'rgba(255, 127, 127, 0.5)' },
                { from: 4, to: 6, color: 'rgba(255, 255, 63, 0.5)' },
                { from: 6, to: 7, color: 'rgba(255, 127, 127, 0.5)' },
                { from: 7, to: 8, color: 'rgba(127, 255, 127, 0.5)' },
                { from: 8, to: 9, color: 'rgba(255, 255, 63, 0.5)' },
                { from: 9, to: 10, color: 'rgba(255, 127, 127, 0.5)' },
                { from: 10, to: 12, color: 'rgba(127, 255, 127, 0.5)' },
            ],
            labels: {
                formatter: function() {
                    switch(parseInt(this.value)) {
                        case 1: return 'Jan';
                        case 2: return 'Feb';
                        case 3: return 'Mar';
                        case 4: return 'Apr';
                        case 5: return 'May';

                        case 12: return 'Dec';
                        default: return 'NaM(' + this.value + ')';

只要使用线性值，就可以设置任何分辨率。 （为了格式化，我建议使用线性整数值而不是日期，以便更轻松地定义/生成服务器端格式化。
