    <h1>A Bar chart that also uses the drawing API</h1>
    
    <p>
        This Bar chart shows a regular bar chart that also makes use of the drawing API to draw a label on the chart.

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

    <script>
        window.onload = function ()
        {
            var bar = new RGraph.Bar({
                id: 'cvs',
                data: [4,8,5,3,2],
                options: {
                    labels: ['Fred','John','James','Louis','Pete'],

                    textAccessible: true
                }
            }).draw();
            
            // Get the X/Y coordinates from the bar chart
            var idx = 2;
            var x   = bar.coords[idx][0] + (bar.coords[idx][2] / 2);
            var y   = bar.coords[idx][1];
            var r   = 15;

            marker = new RGraph.Drawing.Marker1({

                text: 'A',
                options: {
                    tooltips: ['James was the winner by a country mile.'],

    This goes in the documents header:
    <pre class="code">
&lt;script src="RGraph.common.core.js"&gt;&lt;/script&gt;
&lt;script src="RGraph.common.dynamics.js"&gt;&lt;/script&gt;
&lt;script src="RGraph.common.tooltips.js"&gt;&lt;/script&gt;
&lt;script src="RGraph.drawing.marker1.js"&gt;&lt;/script&gt;
&lt;script src="RGraph.bar.js"&gt;&lt;/script&gt;
</pre>
    
    Put this where you want the chart to show up:
    <pre class="code">
&lt;canvas id="cvs" width="600" height="250"&gt;
    [No canvas support]
&lt;/canvas&gt;
</pre>

    This is the code that generates the chart:
    <pre class="code">
&lt;script&gt;
    window.onload = function ()
    {
        var bar = new RGraph.Bar({
            id: 'cvs',
            data: [4,8,5,3,2],
            options: {
                labels: ['Fred','John','James','Louis','Pete'],
                strokestyle: 'rgba(0,0,0,0)',
                textAccessible: true
            }
        }).draw();
        
        <span>// Get the X/Y coordinates from the bar chart</span>
        var idx = 2;
        var x   = bar.coords[idx][0] + (bar.coords[idx][2] / 2);
        var y   = bar.coords[idx][1];
        var r   = 15;

        marker = new RGraph.Drawing.Marker1({
            id: 'cvs',
            x: x,
            y: y,
            radius: r,
            text: 'A',
            options: {
                tooltips: ['James was the winner by a country mile.'],
                highlightFill: 'rgba(255,0,0,0.2)',
                textAccessible: true
            }
        }).draw();
    };
&lt;/script&gt;
</pre>
