在 highcharts 中给定一个简单的日期时间(x)与值(y)图，是否可能 给定 2 个日期作为范围来更改背景颜色？换句话说，每个给定的范围将 用一些特定的颜色定义一个“矩形”。

最佳答案

使用plotBands

例子:

http://jsfiddle.net/gh/get/jquery/1.7.2/highslide-software/highcharts.com/tree/master/samples/highcharts/xaxis/plotbands-color/

$(function () {
$('#container').highcharts({
    chart: {
    },
    xAxis: {        
        plotBands: [{ // mark the weekend
            color: '#FCFFC5',
            from: Date.UTC(2010, 0, 2),
            to: Date.UTC(2010, 0, 4)
        }],
        tickInterval: 24 * 3600 * 1000, // one day
        type: 'datetime'
    },

    series: [{
        data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4],
        pointStart: Date.UTC(2010, 0, 1),
        pointInterval: 24 * 3600 * 1000
    }]
});
});
