A Line chart with a gradient fill

[No canvas support]

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>
    points = 365 * 2;
    data   = [];
    last   = 16;
    max    = 50;

    // Create the data
    for (var i=0; i<points; i+=1) {
        
        last = (RGraph.random(-1,1) + last);
        last = Math.min(last, max);
        last = Math.max(last, 0);
        
        data.push(last);
    }

    new RGraph.Line({
        id: 'cvs',
        data: data,
        options: {
            shadow: null,
            filled: true,
            filledColors: 'Gradient(rgba(255,255,255,0.5):rgba(0,200,200,0.25))',
            xaxisTickmarksCount: 8,
            xaxisLabels: [
                '','Q1 `10','',
                '','\r\nQ2 `10','',
                '','Q3 `10','',
                '','\r\nQ4 `10','',

                '','\r\nQ2 `11','',
                '','Q3 `11','',
                '','\r\nQ4 `11',''
            ],
            backgroundGridVlines: false,
            backgroundGridBorder: false,
            colors: ['rgb(33,200,200)'],
            marginBottom: 50,
            xaxis: false,

        }
    }).draw();
