Dynamic update of multiple series in highcharts

Question

I have a highcharts-chart with four lines (series). I would like to update each series with one point (value) and shift these four lines dynamically (1 in - 1 out) at the same time. This works with one series in the chart perfectly:

chart.series[0].addPoint([x, 5], true, true);

Is there a fast way to add the point to all four lines at once?

You can can update each series on one line, but only make the last one redraw the chart like so:

chart.series[0].addPoint([x, 5], false, true);
chart.series[1].addPoint([x, 5], false, true);
chart.series[2].addPoint([x, 5], false, true);
chart.series[3].addPoint([x, 5], true, true);

Here is a JSFiddle illustrating the concept: http://jsfiddle.net/mkremer90/yZSzZ/
