title: How to force Highcharts to show last label on xAxis?
body: <p>It seems that in a stepped xaxis the normal "showLastLabel" <a href="https://stackoverflow.com/questions/23518720/last-label-is-not-showing-in-stepped-labels-of-highchart">doesn't work</a>. In my case, I am displaying every tenth year only; but if I want to see in any case the latest year, it doesn't work. <a href="http://jsfiddle.net/luftikus143/grg4b6xk/4/" rel="nofollow noreferrer">Here is a fiddle</a>.</p>
  
  <pre><code>$(function () {
  var chart = new Highcharts.Chart(
              {
                  chart:
                  {
                      renderTo: "container",
                      type: "line"
                  },
                  title: 
                  {
                      text: "Emissions of CO2 - from Fossil Fuels - Total (CDIAC)"
                  },
                  xAxis:

                      labels:

                          step: 10
                      },
                      showLastLabel: true,
                      endOnTick: true

                  yAxis:
