拖动轴时如何执行操作？

final CategoryAxis xAxis = new CategoryAxis();
final NumberAxis yAxis = new NumberAxis(1, 21, 0.1);
final LineChart<String, Number> lineChart = new LineChart<String, Number>(xAxis, yAxis);

// What should go in the ???
lineChart.getYAxis().getOnMouseDragged().handle(???)

很简单，只是错过了setOnMouseDragged(event -> {...})处理程序。
