# A basic example of the drawing API marker1 object

This goes in the documents header:

    <script src="RGraph.common.core.js"></script>
    <script src="RGraph.common.tooltips.js"></script>
    <script src="RGraph.common.dynamic.js"></script>
    <script src="RGraph.drawing.marker1.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: [5,8,6,4,3,5,2],
                options: {
                    hmargin: 5,
                    labels: ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday'],
                    textAccessible: true
                }
            }).draw();

            var marker1 = new RGraph.Drawing.Marker1({
                id: 'cvs',
                x: ((550 / 6) * 4) + 25,
                y: line.coords[4][1],
                radius: 35,
                text: 'Woohoo!',
                options: {
                    tooltips: ['Lou'],
                    align: 'left',
                    textAccessible: true,
                    textAccessiblePointerevents: false
                }
            }).draw();
        };
    </script>
