[Solved]-Get categories name of basic column chart-Highcharts

The xAxis categories for the first xAxis for the first chart can be returned with

Highcharts.charts[0].xAxis[0].categories

Here's a real quick and dirty function that given a location and month will alert the y data value:

getSpecificData = function(location, month){
    var chart = Highcharts.charts[0];
    for (var i = 0; i < chart.series.length; i++) {
        if (chart.series[i].name == location){
            for (var j = 0; j < chart.series[i].points.length; j++){
                if (chart.series[i].points[j].category == month){
                    alert(chart.series[i].points[j].y);
                }
            }
        }
    }
}
