  <p>The configuration I use is as simple as that : </p>
  
  <pre><code>var lineChartData = {
              "datasets": [{
                  "label": "defi score",
                  "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 ctx = document.getElementById("chart_per_week").getContext("2d");
          var myLine = new Chart(ctx).Line(lineChartData, {
              responsive: true,
              scaleFontColor: "#FF5972",
              bezierCurve: false
          });
  </code></pre>
