Two charts (on two canvas tags) with tooltips and click events

This goes in the documents header:

<script src="RGraph.common.core.js"></script>
<script src="RGraph.common.dynamic.js"></script>
<script src="RGraph.common.tooltips.js"></script>
<script src="RGraph.line.js"></script>
<script src="RGraph.pie.js"></script>

Put this where you want the chart to show up:

<canvas id="cvs" width="600" height="250">[No canvas support]</canvas>
<canvas id="cvs2" width="200" height="200">[No canvas support]</canvas>

This is the code that generates the chart:

<script>
    window.onload = function ()
    {
        var line = new RGraph.Line({
            id: 'cvs',
            data: [20,30,50,40,30,50,40,30,60,50,10,20],
            options: {
                labels: ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec'],
                tooltips: ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec'],
                eventsClick: function (e, shape)
                {
                    alert('The Line chart click event');
                },
                textAccessible: true
            }
        }).draw()
        
        var pie = new RGraph.Pie({
            id: 'cvs2',
            data: [5,6],
            options: {
                exploded: 5,
                tooltips: ['John', 'Mary'],
                strokestyle: 'rgba(0,0,0,0)',
                eventsClick: function (e, shape)
                {
                    alert('The Pie chart click event');
                }
            }
        }).draw();
    };
</script>
