You need to tell it to also update the second series of data. I couldn’t figure out the smoothing or if it’s possible to smooth once you have > 1 data stream.

Key code added:

var seriesA = this.series[1];

   setInterval(function() {

   var x = (new Date()).getTime(), // current time

   y = Math.random();

   seriesA.addPoint([x, y], true, true);

}, 1000);

I duplicated the call where the series data is added to the chart – changed the series variable to seriesA and then told it to pull the second series of data (series1).

Hope this helps.
