<div id="chartdiv"></div>

// 创建图表实例
var chart = am4core.create("chartdiv", am4charts.XYChart);

// 设置数据源
chart.data = [{
  "date": new Date(2022, 0, 1),
  "value": 100
}, {
  "date": new Date(2022, 0, 2),
  "value": 200
}, {
  "date": new Date(2022, 0, 3),
  "value": 150
}];

// 创建日期轴
var dateAxis = chart.xAxes.push(new am4charts.DateAxis());
dateAxis.renderer.grid.template.location = 0;
dateAxis.renderer.labels.template.location = 0.5;
dateAxis.dateFormats.setKey("day", "M/d/yyyy"); // 设置日期格式为M/d/yyyy

// 创建值轴
var valueAxis = chart.yAxes.push(new am4charts.ValueAxis());

// 创建折线图系列
var series = chart.series.push(new am4charts.LineSeries());
series.dataFields.dateX = "date";
series.dataFields.valueY = "value";

// 添加光滑效果
series.tensionX = 0.8;
series.tensionY = 0.8;

// 添加光滑曲线效果
var bullet = series.bullets.push(new am4charts.CircleBullet());
bullet.circle.radius = 4;
bullet.circle.strokeWidth = 2;
bullet.circle.fill = am4core.color("#fff");

// 添加鼠标悬停提示
series.tooltipText = "{valueY}";

// 设置图表主题
chart.theme = am4themes_animated;
