amcharts-将dateAxis.baseInterval从月份更改为年份没有摘要？

问题描述

当我将baseInterval从月份切换为年份时，我看到了9月份的tooltipText值？如何将所有月份值汇总到年份。我做错了什么？

var dateAxis = chart.xAxes.push(new am4charts.DateAxis());
dateAxis.renderer.minGriddistance = 50;
dateAxis.renderer.grid.template.location = 0.5;
dateAxis.baseInterval = {
count: 1,timeUnit: "year"
}
        
var series = chart.series.push(new am4charts.Lineseries());
series.name = "Installation";
series.datafields.dateX = "day";
series.datafields.valueY = "turnover_installation";
series.tooltipText = "Installation: {valueY.value}";
series.sequencedInterpolation = true;
series.fillOpacity = 0.6;
series.defaultState.transitionDuration = 1000;
series.stacked = true;
series.strokeWidth = 2;

非常感谢！
