Chart.js v2.0: Tooltip only for one dataset
<p>I have graph whit this 3 datasets:</p>

<pre class="lang-js prettyprint-override"><code>this.myChart = new Chart(this.ctx, {
  type: 'bar',
  data: {
    labels: labels,
    datasets: [
      { type: 'line', data: data3 },
      { type: 'bar', data: data1, backgroundColor: "#3EAFD5" },
      { type: 'bar', data: data2, backgroundColor: "#D24B47" }
    ]
  }
}
</code></pre>

<p>How can I do to show tooltip only for first dataset (type: 'line')?</p>
