Tested on 22a scatter graph, may or may not work with other graph types. Best suited to 23situations involving a smaller number of points.24usage -25    <style type="text/css">26    .myCSSClass27    {28        font-size: 9px;29        color: #AD8200;30        padding: 2px;31        opacity: 0.80;32    }33    </style>34    <script type="text/javascript">35    var names = [36        "foo",37        "bar"38    ];39    var data = { data: [[1,1],[2,2]], showLabels: true, labels: names, labelPlacement: "left", labelClass: "myCSSClass" };40    $.plot($("#placeholder), [data], options);41    </script>42For each series that you want labeled you need to set showLabels to true, set labels to an array of label names (strings),43set the labelClass to a css class you have defined for your labels and optionally set labelPlacement to one of "left", "right", 44"above" or "below" (below by default if not specified). Placement can be fine tuned by setting the margins in your label class.45Note: if the labelClass is not explicitly supplied in the development version of flot (> v0.7), the plugin will auto generate46a label class as "seriesLabelx" where x is the 1-based index of the data series. I.e. the first dataseries will be seriesLabel1,47the second seriesLabel2, etc.48For the names, the array should be the same length as the data. If any are missing (null) then the label for that point will49be skipped. For example, to label only the 1st and 3rd points:50    51    var names = ["foo", null, "bar"];52Update: Version 0.253Added support for drawing labels using canvas.fillText. The advantages are that, in theory, drawing to the canvas should be 54faster, but the primary reason is that in some browsers, the labels added as absolutely positioned div elements won't show up55if you print the page. So if you want to print your graphs, you should probably use canvasRender.56The disadvantage is that you lose the flexibility of defining the label with a CSS class.57Options added to series (with defaults):58            canvasRender: false,                // false will add divs to the DOM rather than use canvas.fillText59            cColor: "#000",                     // color for the text if using canvasRender60            cFont: "9px, san-serif",            // font for the text if using canvasRender61            cPadding: 4                         // Padding to add when using canvasRender (where padding is added depends on62                                                // labelPlacement)63Also, version 0.2 takes into account the radius of the data points when placing the labels.64*/65(function ($) {66    function init(plot) {67        plot.hooks.drawSeries.push(drawSeries);68        plot.hooks.shutdown.push(shutdown);69        if (plot.hooks.processOffset) {         // skip if we're using 0.7 - just add the labelClass explicitly.70            plot.hooks.processOffset.push(processOffset);71        }72    }73    function processOffset(plot, offset) {74        // Check to see if each series has a labelClass defined.
