Remove Highlighting Of The Clicked Part In Flot

I'll take as an example this plot: http://www.flotcharts.org/flot/examples/interacting/

As you can see, if you click a point it will remain highlighted. Not an issue with static graphs, but I have a graph that is updated every second.

How could I make this highlighted part disappear after a certain period, e.g. 5 seconds?

This is the flot code for the above chart (clickable elements):

$("#placeholder").bind("plotclick", function (event, pos, item) {
        if (item) {
            $("#clickdata").text(" - click point " + item.dataIndex + " in " + item.series.label);
            plot.highlight(item.series, item.datapoint);
        }
    });

To remove the highlight after 5 seconds, you can use a timer for the unhighlight() function:

$("#placeholder").bind("plotclick", function (event, pos, item) {
    if (item) {
        $("#clickdata").text(" - click point " + item.dataIndex + " in " + item.series.label);
        plot.highlight(item.series, item.datapoint);

        setTimeout(function() {
            plot.unhighlight(item.series, item.datapoint);
        }, 5000);
    }
});
