Highcharts: Change the Legend TItle on drilldown -

-

i'm trying have legend title change when drill-down next level of data.

currently, i'm using click event call function removes existing series , adds new ones, followed chart.redraw().

is possible set legend title using .attr in same function? i've seen few examples use change y-axis or chart title, can't working legend title.

    function redrawlegend(legendtitle) {     chart.legend.attr({         text: legendtitle         }); };

'legendtitle' in case variable have stored drill-down data.

use: chart.legend.title.attr({ text: 'aaa' });

example: http://jsfiddle.net/ag6wq/
