    <div id="placeholder" style="width:600px;height:300px"></div>

    <p>Various point types. Circles are built-in. For other
    point types, you can define a little callback function to draw the
    symbol; some common ones are available in the symbol plugin.</p>

<script id="source" language="javascript" type="text/javascript">
$(function () {
    function generate(offset, amplitude) {
        var res = [];
        var start = 0, end = 10;
        for (var i = 0; i <= 50; ++i) {
            var x = start + i / 50 * (end - start);
            res.push([x, amplitude * Math.sin(x + offset)]);
        }
        return res;
    }

    var data = [
        { data: generate(2, 1.8), points: { symbol: "circle" } },
        { data: generate(3, 1.5), points: { symbol: "square" } },
        { data: generate(4, 0.9), points: { symbol: "diamond" } },
        { data: generate(6, 1.4), points: { symbol: "triangle" } },
        { data: generate(7, 1.1), points: { symbol: "cross" } }
    ];

    $.plot($("#placeholder"), data, {
        series: { points: { show: true, radius: 3 } },
        grid: { hoverable: true }
    });
});
</script>
