# A Line chart with background horizontal bars

This goes in the documents header:

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

Put this where you want the chart to show up:

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

This is the code that generates the chart:

    <script>
        window.onload = function ()
        {
            var line = new RGraph.Line({
                id: 'cvs',
                data: [26,4,-15.5,17,42.5,25],
                options: {
                    labels: ['2007', '2008', '2009', '2010', '2011', '2012'],
                    backgroundHbars: [
                        [-55,-5,'rgba(255,0,0,0.2)'],
                        [-45,-10,'rgba(255,255,0,0.2)'],
                        [-45,90,'rgba(0,255,0,0.2)'],
                        [45,10,'rgba(255,255,0,0.2)'],
                        [55,5,'rgba(255,0,0,0.2)']
                    ],
                    xaxispos: 'center',
                    ymax: 60,
                    linewidth: 5,
                    hmargin: 5,
                    colors: ['black'],
                    textAccessible: true
                }
            }).draw();
        };
    </script>
