如何在区域样条类别highcharts中显示从当前日期起一周的最后七天

var currentDate = new Date(); // 获取当前日期
var oneWeekAgo = new Date(currentDate.getTime() - 7 * 24 * 60 * 60 * 1000); // 计算一周前的日期

var data = [
  { date: '2022-01-01', value: 10 },
  { date: '2022-01-02', value: 20 },
  { date: '2022-01-03', value: 15 },
  // ...
];

var lastSevenDaysData = data.filter(function(item) {
  var itemDate = new Date(item.date);
  return itemDate >= oneWeekAgo && itemDate <= currentDate;
});

lastSevenDaysData = lastSevenDaysData.map(function(item) {
  var itemDate = new Date(item.date);
  return [itemDate.getTime(), item.value];
});

lastSevenDaysData.sort(function(a, b) {
  return a[0] - b[0];
});

Highcharts.chart('container', {
  chart: {
    type: 'areaspline'
  },
  title: {
    text: 'Last Seven Days Data'
  },
  xAxis: {
    type: 'datetime'
  },
  yAxis: {
    title: {
      text: 'Value'
    }
  },
  series: [{
    name: 'Data',
    data: lastSevenDaysData
  }]
});
