# A Line chart in blue

A Line chart in blue surrounded by a black box. The box is added after the main drawing by using the ondraw custom RGraph event.

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: [28,21,26,32,35,36,39,45,47,51,55,74,85],
                options: {
                    labels: ['1950','\n1955','1960','\n1965','1970','\n1975','1980','\n1985','1990','\n1995','2000','\n2005','2010'],
                    colors: ['blue'],
                    noaxes: true,
                    ymax: 100,
                    unitsPost: '%',
                    gutterLeft: 45,
                    gutterBottom: 45,
                    gutterTop: 10,
                    gutterRight: 5,
                    linewidth: 3,
                    hmargin: 7,
                    textAccessible: true,
                    scaleZerostart: true
                }
            }).on('draw',function (obj)
            {
                RGraph.path2(
                    obj.context,
                    ['lw', 1, 'lj', 'miter', 'sr', 45,10,550.01,195] // The .01 is to get around a (possibly now fixed) Chrome oddity
                );
            })
            .draw();
        };
    </script>
