title: Highcharts axis label before first point
body: <p>Good morning,</p>
  
  <p>I'm having a really annoying issue with Highcharts, such that the x-axis label(using datetime) won't start at my first datapoint - as in this image:</p>

  <p>As you can see, the chart label starts at 15. Aug, whereas it shoudl start at 9. Aug.</p>
  
  <p>Setting the startOnTick: true forces the axis label to start on the left, but the label still doesn't correspond to my first point - as in this image:</p>

  <p>Where you can see the label starting at 8.Aug, when it should start at 9. Aug. Better shown in my hourly chart:</p>

  <p>My series type is line and the data takes a [dateutc, decimal] pair. The datetime intervals are not at regular intervals and can range from hourly to daily to monthly.</p>
  
  <pre><code>xAxis: {
    type: "datetime",
    lineWidth: 2,
    //startOnTick: true,
    //showFirstLabel: true
  }
  </code></pre>
