I have one spline updating each minute. What I need to do is to put another spline with different color into the same graphic.
So I just copied the same JavaScript code again, it works fine with a different color but it overwrites the first one. Of course it's to be expected but I don't know what to change to visualize two spline at the same time.
I'm new to JavaScript, so thanks in advance..!
You can use addSeries() function to add new series with separate color: http://api.highcharts.com/highcharts#Chart.addSeries()
