Accepted answer

you need to catch the event. see the chart.events.drillup api doc. to get the series and points in the series you would do something like:

    events: {
        drillup: function (e) {
            console.log(this);
            console.log(this.options.series[0].name);
            console.log(this.options.series[0].data[0].name);
        }
    }

since you did not state which series or points you wanted this is the most general method.

chart: {
         type: 'column',
         events: {
            drillup: function (e) {
                   alert(e.seriesoptions.name);
            }
        }     
    }

from the below line,

e.seriesoptions.name

you will get the series name, which you are loading, by clicking that back button(drill up button).
