如何在用户单击时确定条形图（Highchart）中条形的值？

Question

Currently I have a Highchart that renders according to data in my database. I also currently have a table that renders with the correct values when I pass in a value such as "A" or "C" manually, but I'd like the table to render according to an onClick event, when a user clicks on a bar in my Highchart.

For each corresponding value below, such as @a_sum, I have an array called @a with string values in it that will be passed into the chart.

I've Googled around without much luck. I'm wondering how I get the value of the bar in the char when a user clicks on that specific bar.

Any help would be hugely appreciated.

<script type="text/javascript" charset="utf-8">
var chart1; // globally available
$(document).ready(function () {
    var chart = new Highcharts.Chart({
        chart: {
            renderTo: 'container',
            type: 'bar'
        },
        title : {
            text: "Most Effective Referral Sources"
        },
        xAxis: {
            categories: ['A', 'B', 'C', 'D', 'E', 'F',  'G', 'H', 'I', 'J', 'K', 'L']
        },
        yAxis: {   
        },
        legend: {
            layout: 'vertical',
            floating: true,
            backgroundColor: '#FFFFFF',
            align: 'right',
            verticalAlign: 'top',
            y: 60,
            x: -60
        },
        tooltip: {
            formatter: function() {
                return '<b>'+ this.series.name +'</b><br/>'+
                    this.x +': '+ this.y;
            }
        },
        plotOptions: {
        },
        series: [{
            data: [<%= @a_sum %>, <%= @b_sum %>, <%= @c_sum %>, <%= @d_sum %>,  <%= @e_sum %>, <%= @f_sum %>, <%= @g_sum %>, <%= @h_sum %>, <%= @i_sum %>, <%= @j_sum %>,  <%= @k_sum %>, <%= @l_sum %>]
        }]
    });
});

</script>

It seems like what you want (if I understand you question correctly) is to implement the event in the plotOptions above: http://www.highcharts.com/ref/#plotOptions-column-point-events--click

plotOptions: {
    column: {
         point: {
             events: {
         click: function() {
                     // use this to trigger showing/hiding the specific table you need
                     console.log(this)
                 }
             }
         }
    }
}

For example, this is a sample of the console log I got:

Lc
_high: 417
...
series: c
...
x: 20
y: 33
__proto__: Object

With this.series you should be able to get the parameters on the series whose column you click, and then call your "enableTableForDataSeries" function to enable the specific data series.
