Hiding labels and ticks for small pie slices

This demo shows how we can use an adapter to automatically hide labels and ticks of small pie chart slices.

Relevant code

series.labels.template.adapters.add("y", function(y, target) {
  let dataItem = target.dataItem;
  if (dataItem) {
    var tick = dataItem.get("tick");
    if (tick) {
      if (dataItem.get("valuePercentTotal") < 1) {
        target.set("forceHidden", true);
        tick.set("forceHidden", true);
      }
      else {
        target.set("forceHidden", false);
        tick.set("forceHidden", false);
      }
    }
    return y;
  }
});

series.labels.template.adapters.add("y", function(y, target) {
  var dataItem = target.dataItem;
  if (dataItem) {
    var tick = dataItem.get("tick");
    if (tick) {
      if (dataItem.get("valuePercentTotal") < 1) {
        target.set("forceHidden", true);
        tick.set("forceHidden", true);
      }
      else {
        target.set("forceHidden", false);
        tick.set("forceHidden", false);
      }
    }
    return y;
  }
});
