I\'m unable to figure out myself or find a proper example on how to perform live updates in jqPlot in a similar way as shown in this highcharts example.
I added an example on JSFiddle jsfiddle.net/meccanismocomplesso/QAr4r/ which reproduces the example you linked.
I've tried to keep the topic as more general as possible. If you need more explanation read this article about that.
var plot1 = $.jqplot('myChart', [data], options);
...
plot1.series[0].data = data; // update the graph
