Using Chart.js 2.0, display line chart values
<p>I am trying to get Chart.js 2.0 to display point values in a line chart using the animation onComplete function.  I found a post making it work using 1.02, <a href="https://stackoverflow.com/questions/31631354/how-to-display-data-values-on-chart-js">how to display data values on Chart.js</a>, but I am unable to make it work in v2.  </p>

<p>My failing fiddle is at <a href="https://jsfiddle.net/7oghxjxs/4/" rel="nofollow noreferrer">Line Chart v2</a>.  Any help would be appreciated.</p>

<pre><code>var chartData = {


labels: ["January", "February", "March", "April", "May", "June"],
  datasets: [{
    label: "Buttons",
    strokeColor: "#79D1CF",
    tension: 0,
    fill: false,
    data: [60, 80, 81, 56, 55, 40]
  }, {
    label: "Zipppers",
    strokeColor: "rgba(255,255,0,1)",
    tension: 0,
    fill: false,
    data: [50, 75, 42, 33, 80, 21]
  }]
};

var options = {
  animation: {
    onComplete: function() {
      var ctx = this.chart.ctx;
      ctx.font = this.scale.font;
      //alert(ctx.font);
      ctx.fillStyle = this.scale.textColor
      ctx.textAlign = "center";
      ctx.textBaseline = "bottom";
      var datasetName = chartData.data.datasets[0].label;
      alert(chartData.data.datasets[0].label)
      myLine.data.datasets.forEach(function(dataset) {
        ctx.fillStyle = dataset.strokeColor;
        dataset.points.forEach(function(points) {
          ctx.fillText(points.value, points.x, points.y - 10);
        });
      })
    }
  }
};


Chart.defaults.global.responsive = true;
Chart.defaults.global.maintainAspectRatio = true;
Chart.defaults.global.title.display = true;

var ctx = document.getElementById("myChart1").getContext("2d");
var myLine = new Chart(ctx, {
