I had the same issue, try injecting the NgZone class on your component constructor

constructor(private zone: NgZone) {

)

then, use the runOutsideAngular method from NgZone to put in a callback the draw method from google charts, do something like this.

this.zone.runOutsideAngular(() => {
    var chart = new google.visualization.PieChart(nativeElement);
    chart.draw(dataTable, options);
})

This make the executed code don't fire angular detection changes. Apply this for each chart you make. I hope find this helpful.
