Amcharts4 -如何显示/隐藏单个列categoryAxis标签？

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

// 设置数据
chart.data = [{
  "category": "A",
  "value": 10
}, {
  "category": "B",
  "value": 20
}, {
  "category": "C",
  "value": 15
}];

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

// 创建valueAxis
var valueAxis = chart.yAxes.push(new am4charts.ValueAxis());

// 创建柱状图系列
var series = chart.series.push(new am4charts.ColumnSeries());
series.dataFields.valueY = "value";
series.dataFields.categoryX = "category";

// 获取第一个柱状图系列的categoryAxis标签
var label = categoryAxis.renderer.labels.getIndex(0);

// 隐藏第一个柱状图系列的categoryAxis标签
label.disabled = true;
