[Solved]-programmatically click on column in Highcharts-Highcharts

you cna use built-in function for firing events: firepointevent(type). see: http://jsfiddle.net/7xehw/31/

for first column it is: chart.series[0].data[0].firepointevent('click');

firepointevent is not part of docs, but it's used internally.
