如何在amCharts上同时显示月份和年份？

var categoryAxis = chart.xAxes.push(new am4charts.CategoryAxis());
categoryAxis.dataFields.category = "month";

var dateAxis = chart.xAxes.push(new am4charts.DateAxis());
dateAxis.dataFields.date = "year";
dateAxis.renderer.minGridDistance = 50; // 设置日期轴上的最小网格间距

var data = [{
  "month": "January",
  "year": new Date(2022, 0, 1) // 使用Date对象表示年份
}, {
  "month": "February",
  "year": new Date(2022, 1, 1)
}, {
  "month": "March",
  "year": new Date(2022, 2, 1)
}, ...];

chart.data = data;
categoryAxis.dataFields.category = "month";
dateAxis.dataFields.date = "year";

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

// 创建类别轴
var categoryAxis = chart.xAxes.push(new am4charts.CategoryAxis());
categoryAxis.dataFields.category = "month";

// 创建日期轴
var dateAxis = chart.xAxes.push(new am4charts.DateAxis());
dateAxis.dataFields.date = "year";
dateAxis.renderer.minGridDistance = 50;

// 创建数据源
var data = [{
  "month": "January",
  "year": new Date(2022, 0, 1)
}, {
  "month": "February",
  "year": new Date(2022, 1, 1)
}, {
  "month": "March",
  "year": new Date(2022, 2, 1)
}, ...];

// 绑定数据源
chart.data = data;

// 配置其他图表属性
// ...

// 显示图表
chart.exporting.menu = new am4core.ExportMenu();
chart.exporting.menu.align = "right";
chart.exporting.menu.verticalAlign = "top";
chart.exporting.menu.items = [{
  "label": "Export",
  "menu": [{
    "label": "Image",
    "menu": [{
      "label": "PNG",
      "click": function() {
        chart.exporting.export("png");
      }
    }, {
      "label": "JPG",
      "click": function() {
        chart.exporting.export("jpg");
      }
    }, {
      "label": "SVG",
      "click": function() {
        chart.exporting.export("svg");
      }
    }]
  }, {
    "label": "Print",
    "click": function() {
      chart.exporting.print();
    }
  }]
}];
