echarts 曲线图表背景区域划分？

类似于图中的echarts 曲线图表背景区域划分，分为4块不同的颜色，这个怎么弄呢，谢谢

                         data: [
                                [{
                                    name: '',
                                    xAxis: 0,
                                    yAxis: 0,
                                    itemStyle: {
                                        color: 'rgba(233,250,140,0.8)'
                                    },
                                }, {
                                    xAxis: 80,
                                    yAxis: 200
                                }
                            ],
                                [{
                                    name: '',
                                    yAxis: 200,
                                    itemStyle: {
                                        color: 'rgba(153,236,116,0.8)'
                                    },
                                }, {
                                    yAxis: 450,
                                }],
                                [{
                                    name: '',
                                    yAxis: 450,
                                    itemStyle: {
                                        color: 'rgba(233,250,140,0.8)'
                                    }
                                }, {
                                    yAxis: 1000,
                                }]
                            ]

效果图如下：

没有关于x轴分割

Answer 1

可以使用自定义系列画出背景

Answer 2

改一下可以用

option = {
    tooltip: {
        trigger: 'axis'
    },
    xAxis: {
        data: [
            '2019-12-14 00:00:00', 
            '2019-12-15 00:00:00', 
            '2019-12-16 00:00:00', 
            '2019-12-17 00:00:00', 
            '2019-12-18 00:00:00', 
            '2019-12-19 00:00:00', 
            '2019-12-20 00:00:00'
        ],
        axisLabel: {
            formatter: function(res) {
                return res.split(" ")[0] + "\n" + res.split(" ")[1];
            }
        }
    },
    yAxis: {
        
    },
    series: [{
        name: "测试标域",
        smooth: true,
