Lazy highcharts and rails

I'm using the Lazy HighCharts gem in my rails application and I have an array set up for my categories on my xAxis. I want to show just the first and last array, having the first appear on the left hand side and the last appear on the far right. Is this possible?

dates = [10,11,12,13,14,15,16]
@graph = LazyHighCharts::HighChart.new('graph') do |f|
      f.xAxis(:categories => dates)
      f.series(:type => 'spline', :name => 'Average', :data => [1,2,3,4,5,6,7], :color => '#b20838', marker: {enabled: false})
      f.legend({:align => 'right', :y => 10, :verticalAlign => 'top', :floating => "true", :borderWidth => 0})
    end

So instead of showing all dates on x-axis :

I would like the first and last array to show.

Try to use :tickPositions => [0, lengthOfCategories-1] for xAxis.

If you can find out the first and last values of the labels and store them in variables before itself, then you can do some thing like this http://jsfiddle.net/E7GBd/ using 

formatter: function(){}

Hope this will help you.
