title: Setting Highcharts maximum Y value to an exact amount without rounding
body: <p>Every time I set my min and max values in Highcharts, I never get graphs with the exact min and max that I sent, but always something somewhat close. It seems as though Highcharts is picking a interval range for the axes and if my maximum doesn't conform to the right interval, it gets ignored or rounded off.</p>
  
  <p>For example, if I set a min of 0 and a max of 3125 for a Y axis, I get a Y axis starting with 0 then going up in increments of 500 to a maximum of 3500, which is not at all what I want.</p>
  
  <p>Can I get the chart to use an exact maximum or will it always round up in some wierd way?</p>
