A basic Scatter chart with an appropriate scale

[No canvas support]

This goes in the documents header: 
<script src="RGraph.common.core.js"></script>
<script src="RGraph.scatter.js"></script>
Put this where you want the chart to show up: 
<canvas id="cvs" width="600" height="200">
    [No canvas support]
</canvas>
This is the code that generates the chart: 
<script>
    new RGraph.Scatter({
        id: 'cvs',
        data: [
            [31,7],[51,1],[132,2],[166,3],[311,4],[322,5],[56,6],[10,5],[355,6],[124,7],
            [52,6],[53,1],[225,3],[311,5],[144,2],[133,5]
        ],
        options: {
            xmax: 365,
            labels: ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec']
        }
    }).draw();
</script>
