Dear all,
I have a problem to click the slice of pie chart and I wanna get the value
and slice color.
I know how to get the value but I don't known which method or attribute can
I use to get the color I selected.
this is the related script:
var chart = new
google.visualization.PieChart(document.getElementById('chart_div'));
//click slice to show the value and color
function selectHandler() {
var selectedItem = chart.getSelection()[0];
if (selectedItem) {
var val = data.getValue(selectedItem.row, 0);
alert('value: ' + val);
}
}
google.visualization.events.addListener(chart, 'select', selectHandler);
Please help me, thanks!
Brian
