# A dual color Line chart

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: [5,4,1,6,null,null,null],
                options: {
                    labels: ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday'],
                    colors: ['black'],
                    title: 'A dual color line chart',
                    tickmarks: 'filledcircle',
                    ticksize: 5,
                    shadow: false,
                    gutterTop: 35,
                    gutterRight: 30,
                    gutterLeft: 30,
                    textAccessible: true
                }
            }).draw();

            var line2 = new RGraph.Line({
                id: 'cvs',
                data: [null,null,null,6,5,4,3],
                options: {
                    colors: ['red'],
                    tickmarks: 'filledcircle',
                    ticksize: 5,
                    shadow: false,
                    backgroundGrid: false,
                    noaxes: true,
                    gutterTop: 35,
                    gutterRight: 30,
                    gutterLeft: 30,
                    textAccessible: true
                }
            }).draw();
        };
    </script>
