如何让图表使用amcharts为常量0值画一条线？

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

// 创建数据源对象
var data = [];

// 添加常量0值的数据点
data.push({ value: 0 });

// 设置图表的数据源
chart.data = data;

// 创建用于绘制线条的图形对象
var lineSeries = chart.series.push(new am4charts.LineSeries());
lineSeries.dataFields.valueY = "value";
lineSeries.dataFields.categoryX = "category";

// 设置线条的属性
lineSeries.stroke = am4core.color("#FF0000");
lineSeries.strokeWidth = 2;

// 在图表的"init"事件中绘制图形
chart.events.on("inited", function() {
  chart.draw();
});
