  <p>This is the code I'm using:</p>
  
  <pre><code>var myChart = new Chart.Line(ctx, {
      type: 'line',
      data: {
          labels: ["JAN", "FEB", "MAR", "APR", "MAY", "JUN", "JUL", "AUG", "SEP", "OCT", "NOV", "DEC", ""],
          datasets: [{
              data: [5, 10.5, 18.2, 33.9, 121.2, 184.9, 179.9, 196.1, 158.3, 166.3, 66.4, 20.6, null],
              pointLabelFontSize : 4,
              borderWidth: 2,
              fill: false,
              lineTension: .3,
              borderColor: "#f37029",
              borderCapStyle: 'round',
              borderDash: [],
              borderDashOffset: 0.0,
              borderJoinStyle: 'bevel',
              pointBorderColor: "#f37029",
              pointBackgroundColor: "#f37029",
              pointBorderWidth: 1,
              pointHoverRadius: 4,
              pointHoverBackgroundColor: "rgba(220,220,220,1)",
              pointHoverBorderColor: "rgba(220,220,220,1)",
              pointHoverBorderWidth: 2,
              pointRadius: 4,
              pointHitRadius: 10,
              spanGaps: false,
          }]
      },
      options: {
          scales: {
              xAxes: [{
                  gridLines: {
                      offsetGridLines: true,
                      display: false,
                      borderDash: [6, 2],
                      tickMarkLength:5
                  },
                  ticks: {
                       fontSize: 8,
                       labelOffset: 10,
                       maxRotation: 0
                  }}],
              yAxes: [{
                  gridLines: {
                      display:false
                  },
                  ticks: {
                      beginAtZero: true,
                      max: 200,
                      min: 0,
                      stepSize: 20,
                      fontSize: 8
                  }
              }]
          },
          legend: {
              display: false
          },
          responsive: false,
          maintainAspectRatio: true
      }
  });
  </code></pre>
  
  <p>I would like to apply that offset to all the points, in the image I just added an arrow to the JAN/DEC but I would like to apply it to all of them. </p>
  
  <p>I tried adding a null data, the problem is that I don't want to show the first dashed grid.</p>
