You can calculate it using the scale property. Here is something that draws a blue circle at those points after the animation completes.
onAnimationComplete: function () {
for (var i = 0; i < this.scale.valuesCount; i++) {
// get the poitn position
var pointLabelPosition = this.scale.getPointPosition(i, this.scale.calculateCenterOffset(this.scale.max) + 5);
// draw a circle at that point
this.chart.ctx.beginPath();
this.chart.ctx.arc(pointLabelPosition.x, pointLabelPosition.y, 5, 0, 2 * Math.PI, false);
this.chart.ctx.fillStyle = '#77e';
this.chart.ctx.fill();
this.chart.ctx.stroke();
}
}
