How to correct mouse event in Highcharts

Question

I am trying to plot xy line in which y axis is reversed and I am getting plot but mouse event I am unable to correct it it is showing reverse event, and I want to find min and mix of axis automatically how this can be done? And how to bring x axis on top?

This is my code:

JS

$(function () {
var chart = new Highcharts.Chart({
    chart: {
        renderTo: 'container',
        zoomType: 'xy',
        marginLeft: 50,
        marginBottom: 90
    },

   // How to get minmax automatically zooming is a issue
   // reverse is true
    yAxis: {
        reversed: true,
        min:0,max:50
    },
    plotOptions: {
        series: {
            stacking: 'normal'
        }
    },

   series: [
           {
                   name: '01-Jan-2014',
                   data: [[30,0],[28,10]]
           }
           ]
});
});

HTML

  <script src="http://code.highcharts.com/highcharts.js"></script>
  <div id="container" style="height: 400px"></div>

Here is a JS Fiddle.

Whether its possible to pass string inside series ? may be my question is silly please tell me whether its possible, like below I am interested

   string mystring = "{
                 name: '01-Jan-2014',
                 data: [[28, 10],[30, 0]]
               },
               {
                 name: '01-Jan-2014',
                 data: [[28, 10],[30, 0]]
               }"

In series part of code I would like to do like below

                 series: [ 
                             mystring
                         ]

Expected output from this array, sorted y axis GOOD PATTERN - Fiddle but mouse movement is not working

data:[
[ 25.290,1.000 ],
[ 25.240,2.000 ],
[ 25.210,3.000 ],
[ 25.190,4.000 ],
[ 25.180,5.000 ],
[ 25.170,6.000 ],
[ 25.160,7.000 ],
[ 25.310,8.000 ],
[ 25.210,9.000 ],
[ 25.170,10.000 ],
[ 25.160,11.000 ],
[ 25.160,12.000 ],
[ 25.150,13.000 ],
  ]

here I sorted xaxis - mouse event is alright but plot pattern (line) is not the one which I expect BAD PATTERN - Fiddle

   data:[
[ 25.150,13.000 ],
[ 25.160,12.000 ],
[ 25.160,11.000 ],
[ 25.160,7.000 ],
[ 25.170,6.000 ],
[ 25.170,10.000 ],
[ 25.180,5.000 ],
[ 25.190,4.000 ],
[ 25.210,9.000 ],
[ 25.210,3.000 ],
[ 25.240,2.000 ],
[ 25.290,1.000 ],
[ 25.310,8.000 ],
  ]

Answers:

• you have errors in JS console - fix them (sort data ascending by x-value!)
• to set min and max, just don't set anything, Highcharts will calculate extremes
• to display xAxis on top, set opposite: true

Demo: http://jsfiddle.net/2xLvY/1/

var chart = new Highcharts.Chart({
    chart: {
        renderTo: 'container',
        zoomType: 'xy',
        marginLeft: 50,
        marginBottom: 90
    },

    yAxis: {
        reversed: true,
        //min: 0,
        //max: 50
    },
    plotOptions: {
        series: {
            stacking: 'normal'
        }
    },
    xAxis: {
        opposite: true  
    },
    series: [{
        name: '01-Jan-2014',
        data: [
            // NOTE: proper order, first x-value is lower that second
            [28, 10],
            [30, 0]
        ]
    }]
});
