        subtitle: {

                $('#Sdate').html( Highcharts.dateFormat(null, e.min));
                $('#Edate').html( Highcharts.dateFormat(null, e.max));


            }
        }

我自己找到解决办法

  xAxis: {
        events: {
            setExtremes: function(e) {

                $('#Sdate').html( Highcharts.dateFormat(null, e.min));
                $('#Edate').html( Highcharts.dateFormat(null, e.max));



            },
            afterSetExtremes:function(e)
            {
                  var chart = $('#container').highcharts(),
                 extremes = chart.yAxis[0].getExtremes();
                   $('#HiestTemp').html(extremes.dataMax);
                  $('#LowestTime').html(extremes.dataMin);


            }
        }
    },
