How to add in zero values into a time series in c3.js
<p>Are there any way to add zero values into a time series in c3.js
In example you can see, that 2016-01-07 is missed. Can we display such missed dates with zero values?</p>

<pre><code>var jsonData = [{"id": 569, "date": "2016-01-10", "data1": 1, "data2": 0}, {"id": 569, "date": "2016-01-06", "data1": 96, "data2": 22}, {"id": 569, "date": "2016-01-08", "data1": 24, "data2": 1}, {"id": 569, "date": "2016-01-09", "data1": 1, "data2": 0}, {"id": 569, "date": "2016-01-11", "data1": 43, "data2": 2}, {"id": 569, "date": "2016-01-12", "data1": 10, "data2": 1}] 

 var chart = c3.generate({
      bindto: '#chart',
      data: {
        json: jsonData,
        keys: {
          x: 'date',
          value: ['data1', 'data2']
        }
      },
      axis: {
        x: {
          type: 'timeseries',
          tick: {
            format: function (x) { 
            return x.toLocaleDateString('en-GB');}
          }
        }
      },
      subchart: {
        show: true
      },
      zoom: {
        enabled: true
      }
    });
</code></pre>
