title: how to disable last/max value shown on x axis in chart js?
body: <p>Hi I have a list of dataset of every hour in a day, like below:</p>
  
  <pre><code>{"x":"2017-10-14T00:00:00","y":95},{"x":"2017-10-14T01:00:00","y":62},...,{"x":"2017-10-14T23:00:00","y":23}
  </code></pre>
  
  <p>I would like to show them in a four-hour time unit on x-axis so settings are like this:</p>
  
  <pre><code>scales: {
      xAxes: [{
          type: 'time',
          time: {
              displayFormats: {
                  'hour': 'HH:mm'
              },
              unit: 'hour',
              stepSize: 4
          }
      }]
  }
  </code></pre>
  
  <p>However, chart js would display last/max value '23:00' at the end of x-axis which is quite annoying because every tick is 4-hour difference. May I ask how to disable last/max value on x axis?</p>
