Using [Chart.js](http://www.chartjs.org/) you can create line charts and for that you have to privde labels and datasets. for example:

```
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],
        }
    ]
};

```

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?

What if one data entry contains a number and a time:

```
Entry {
    number: 127
    time: 10:00
}

```

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?
