Example

<script>
    // The Bipolar chart takes two arrays of data - one for the left side and one for the right.
    var left  = [5,6,8,9,12,13,4,9];
    var right = [5,8,4,11,15,26,13,16];
    
    var bipolar = new RGraph.Bipolar({
        id: 'cvs',
        left: left,
        right: right,
        options: {
            colors: ['red'],
            hmargin: 3,
            labels: ['Barry', 'John', 'Fred', 'George', 'Rich', 'Larry', 'John', 'Mike'],
            titleLeft: '2007',
            titleRight: '2008',
            gutterBottom: 45
        }

Methods

This method when used in an event will return the details of the bar that was clicked on moused over (if any). It returns:

• The X coordinate
• The Y coordinate
• The width
• The height
• The index of the bar (starting at 0)

The shape also includes textual indexes like this: shape['object'] And they are:

• object
• x
• y
• width
• height
• tooltip
• index

This method can be used to get an appropriate X coordinate for a value when you're doing custom drawing on the chart. It returns an array containing two values - one for each side - and it returns null if the value is out of range.

This method can be used to set an event listener on an object. It operates in a similar way to the jQuery .on() function - the first argument is the event you wish to attach to and the second is the handler function. For example:

.on('draw', function (obj)
{
    // Put event code here
});

The exec function is documented here.

Animation Effects

<script>
    window.onload = (function ()
    {
        /**
        * Optional callback function that's called when the effect is complete
        */
        function myCallback (obj)
        {
            // ...
        }
    
    
        var left  = [4,8,6,3,1,2,5];
        var right = [15,13,18,19,12,16,14];
    
        var bipolar = new RGraph.Bipolar({
            id: 'cvs',
            left: left,
            right: right,
            options: {
                gutterCenter: 135,
                titleLeft: 'August 2013',
                titleRight: 'August 2014',
                textSize: 16,
                textColor: '#666',
                labels: ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday'],
                colors: ['gradient(red:red:red:#a00:#a00:#a00:#600:#a00:red:red:red)']
            }
        }).grow({frames: 60}, myCallback);
        //}).wave({frames: 60}, myCallback);
    });
