按amcharts4中的所有日期时间而不是小时显示日期轴

// 创建日期时间轴对象
var dateAxis = chart.xAxes.push(new am4charts.DateAxis());

// 设置日期时间轴的类型为"DateAxis"
dateAxis.renderer.grid.template.location = 0;
dateAxis.renderer.minGridDistance = 50;

// 设置日期轴的粒度为天
dateAxis.baseInterval = {
  timeUnit: "day",
  count: 1
};

// 格式化日期轴的标签显示
dateAxis.dateFormats.setKey("day", "MM-dd");

// 创建一个序列并绑定到日期时间轴
var series = chart.series.push(new am4charts.LineSeries());
series.dataFields.dateX = "date";
series.dataFields.valueY = "value";
