title: How to disable a tooltip for a specific dataset in ChartJS
body: <p>I displaying a chart where two types are included. Now I want to hide the toolbar for one dataset. I saw some discussion like this on <a href="https://github.com/chartjs/Chart.js/issues/1889" rel="noreferrer">GitHub</a>, but this doesn't bring me further. </p>
  
  <p>Here is an example of my Chart:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>Chart.defaults.global.legend.display = false;
  var ctx = document.getElementById("chart").getContext("2d");
  var data = {
    labels: ["Januar","Februar","März","April","Mai","Juni","Juli","August","September","Oktober","November","Dezember"],
    datasets: [
       {
         label: "Test",
         type: 'bar',
         backgroundColor: "#F29220",
         borderColor: "#F29220",
         data: [4,1,1,2,2,2,2,2,2,2,2,1]
       },
       {
         label: "Test2",
         type: 'bar',
         backgroundColor: "#F29220",
         borderColor: "#F29220",
         data: [4,0,0,0,0,0,0,0,0,0,0,0]
       },
       {
         label: "",
         type: 'line',
         fillColor: "rgba(220,220,220,0)",
         pointColor: "rgba(220,220,220,0)",
         borderColor: "#FF0000",
         tooltip: false,
         data: [100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100]
       }]
    };
    var myBarChart = new Chart(ctx, {
      type: 'bar',
      data: data,
      options: {
         scales: {
            xAxes: [{
               stacked: true,
               ticks: {
                  fontColor: '#000',
               }
            }],
            yAxes: [{
               stacked: true,
               ticks: {
                  beginAtZero: true,
                  fontColor: '#000',
                  callback: function(label, index, labels) {
                     return label + '%';
                  }
               },
            }]
         },
         elements: {
            point:{
               radius: 0
            }
         },
         tooltips: {
            enabled: true,
            mode: 'single',
            callbacks: {
               label: function(tooltipItems, data) {
                   return data.datasets[tooltipItems.datasetIndex].label + ': ' + tooltipItems.yLabel + ' %';
            }
         }
      }
   }
   });</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.5.0/Chart.min.js"&gt;&lt;/script&gt;
  &lt;canvas id="chart" width="740" height="370"&gt;&lt;/canvas&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>How can I hide the tooltip just for the line chart? As you can see in the code, I already tried to insert the attribute "tooltip", but this doesn't work.</p>
