样式一： 

Highcharts.chart('container', {  chart: {    type: 'column'  },  title: {    text: ''  },  credits: {    enabled: false  },  xAxis: {    plotBands: [{      id: 'first-category',      color: '#A9CDD9',      from: -0.5,      to: 2.5    }, {      id: 'second-category',      color: '#A9D9BB',      from: 2.5,      to: 6.5    }],    categories: [{      name: 'First',      categories: ['One', 'Two', 'Three']    }, {      name: 'Second',      categories: ['Four', 'Five', 'Six', 'Seven']    }],    labels: {      rotation: 0    }  },  yAxis: {    title: {      text: ''    }  },  series: [{    data: [10, 10, 10, 10, 10, 10, 10]  }]});

样式二：

columnChart.chartConfig.xAxis.plotBands = [            {                from:0,                to:3,                borderColor:$rootScope.deepxray_app.color.danger,                borderWidth:1,                label:{                    text:"区域1",                }            },            {                from:3.1,                to:7,                borderColor:$rootScope.deepxray_app.color.success,                borderWidth:1,                label:{                    text:"区域1",                }            }        ]
