[Solved]-How to move tooltip position in Highchart?-Highcharts

I am able to fix this issue using Tooltip.positioner as following -

tooltip: {

    formatter: function() {
        return '<b>' + this.x + '</b><br/>' +
            this.series.name + ': ' + this.y + '<br/>' +
            'Total: ' + this.point.stackTotal;
    },
    positioner: function(labelWidth, labelHeight, point) {
        var tooltipX = point.plotX + 20;
        var tooltipY = point.plotY - 30;
        return {
            x: tooltipX,
            y: tooltipY
        };
    }
},
