title: Chart.js : straight lines instead of curves
body: <p>I'm using Chart.JS to plot a dataset,</p>
  
  <p>However I got a smooth effect !</p>
  
  <p>Here is the curve I've got : </p>
  
  <p><a href="https://i.stack.imgur.com/OW5PD.png" rel="noreferrer"><img src="https://i.stack.imgur.com/OW5PD.png" alt="enter image description here"></a></p>
  
  <p>Here is my code : </p>
  
  <pre class="lang-js prettyprint-override"><code>function plotChart(data, labels) {
  
      var lineChartData = {
          "datasets": [{
              "data": data,
              "pointStrokeColor": "#fff",
              "fillColor": "rgba(220,220,220,0.5)",
              "pointColor": "rgba(220,220,220,1)",
              "strokeColor": "rgba(220,220,220,1)"
          }],
          "labels": labels
      };
  
      var myLine = new Chart(document.getElementById("canvas").getContext("2d")).Line(lineChartData);
  
  }
  </code></pre>
  
  <p>How can I have straight lines instead of curves ? </p>
  
  <p>Thank you</p>
