如何防止amChart折线图自动分组数据？

am4core.useTheme(am4themes_animated);

let chart = am4core.create("chartdiv", am4charts.XYChart);

// 添加数据
chart.data = [
  { date: new Date(2020, 0, 1), value: 10 },
  { date: new Date(2020, 0, 2), value: 20 },
  // 更多数据...
];

// 创建类别轴
let categoryAxis = chart.xAxes.push(new am4charts.CategoryAxis());
categoryAxis.dataFields.category = "date";
categoryAxis.groupData = false; // 关键设置，禁用自动分组

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

// 创建系列
let series = chart.series.push(new am4charts.LineSeries());
series.dataFields.categoryX = "date";
series.dataFields.valueY = "value";

chart.cursor = new am4charts.XYCursor();

categoryAxis.groupData = true;
categoryAxis.groupCount = 10; // 设置每10个数据点为一组
