Hello,
I created a bar chart (codes are below). I want to add a function on the
chart: if users want to hide a bar from the chart, how to realize it? Is
there a "x" button in the each bar which can be clicked to hide the bar
(the data don't be deleted, just hide)?
Thank you very much.

<script type="text/javascript">
google.load("visualization", "1", {packages:["corechart"]});
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Year', 'Sales', 'Expenses'],
['2004', 1000, 400],
['2005', 1170, 460],
['2006', 660, 1120],
['2007', 1030, 540]
]);
var options = {
title: 'Company Performance',
vAxis: {title: 'Year', titleTextStyle: {color: 'red'}}
};
var chart = new
google.visualization.BarChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
