回答1:

Finally I got idea from chart-events and modified my code.

class AppComponent {
    constructor(private http: Http) {
        http.get('https://cdn.rawgit.com/gevgeny/angular2-highcharts/99c6324d/examples/aapl.json').subscribe(res => {
            this.options = {
              chart:{
                  },
                title : { text : 'AAPL Stock Price' },   
                series : [{
                    name : 'AAPL', 
                    data : res.json(), 
                    tooltip: {
                        valueDecimals: 2 
                    }
                }]
            };
        });
    }
    options: Object;
    onChartload (e) {
      e.context.renderer.text('Series 1', 100, 170)
              .attr({
                  rotation: -25
              })
              .css({
                  color: '#4572A7',
                  fontSize: '16px'
              })
              .add();

    }
}
