Hi Team

Please let me know how to add doubleclick event to bar chart or any type of chart

Yours Sincerely
Soujanya.

There's no native double click event but you can add one like this:

myObject = new RGraph.Bar({
    id: 'cvs',
    data: [9,10,6,8,4,6,3],
    options: {
        xaxisLabels: ['Hoolio','Gary','Tom','Mark','Karl','Pob','Bob'],
        marginInner: 20,
        backgroundGridBorder: false,
        backgroundGridVlines: false,
        yaxis: false,
        title: 'Double click event listener added to the chart',
        titleBold: true
    }
}).draw();

// This is the DOM1 method of adding events
myObject.canvas.ondblclick = function (e)
{
    var obj = e.target.__object__;
    var shape = obj.getShape(e);

    if (shape) {
        alert('A bar was clicked with index: ' + shape.dataset);
    }
}

// And this is the DOM2 method of adding event listeners
myObject.canvas.addEventListener('dblclick', function (e)
{
    var obj = e.target.__object__;
    var shape = obj.getShape(e);
    if (shape) {
        alert('[DOM2 event listener] A bar was clicked with index: ' + shape.dataset);
    }
});
