var b = "30";
var c = "10";
var name1 = "A";

    var ykeys;
    var barColor;
    if (c> b  )  {
        ykeys = ['a', 'e'];
        barColor = ['#3FBF3F', '#983838'];
    } else {
        ykeys = ['e', 'a'];
        barColor = ['#983838', '#3FBF3F'];
    }
    var xChart = Morris.Bar({



        element: 'xChart',
        barColors: barColor,
        data: [

             { y: name1, e:c, a: b}



 ],  

        xkey: 'y',
        ykeys: ykeys,
        labels: [
            'Amount1',
            'Amount2'
        ],
        stacked: true,
        hideHover: "always",
        barSizeRatio: 1,
        numLines: 1,
        axes: 'x',
    }).on('click', function(i, row) {        
          var url = "www.google.com";

           window.location = url;
 });
