title: Chart.js Line-Chart with different Labels for each Dataset
body: <p>Using <a href="http://www.chartjs.org/" rel="noreferrer">Chart.js</a> you can create line charts and for that you have to privde labels and datasets. for example:</p>
  
  <pre><code>var data = {
      labels: ["January", "February", "March", "April", "May", "June", "July"],
      datasets: [
          {
              label: "My First dataset",
              fill: false,
              lineTension: 0.1,
              backgroundColor: "rgba(75,192,192,0.4)",
              borderColor: "rgba(75,192,192,1)",
              borderCapStyle: 'butt',
              borderDash: [],
              borderDashOffset: 0.0,
              borderJoinStyle: 'miter',
              pointBorderColor: "rgba(75,192,192,1)",
              pointBackgroundColor: "#fff",
              pointBorderWidth: 1,
              pointHoverRadius: 5,
              pointHoverBackgroundColor: "rgba(75,192,192,1)",
              pointHoverBorderColor: "rgba(220,220,220,1)",
              pointHoverBorderWidth: 2,
              pointRadius: 1,
              pointHitRadius: 10,
              data: [65, 59, 80, 81, 56, 55, 40],
          }
      ]
  };
  </code></pre>
  
  <p>The Problem here is that you have a fix amount of labels (7 in this case) and you also need to provide 7 data entries for each dataset. Now what if you have an unknown amount of labels and data entries?</p>
  
  <p>What if one data entry contains a number and a time:</p>
  
  <pre><code>Entry {
      number: 127
      time: 10:00
  }
  </code></pre>
  
  <p>What if you want to show all times on the X-Axis and all Numbers on the Y-Axis sorted by the time on the X-Axis. Is that possible with Chart.js?</p>
