Chart not moving fluently when adding value to two lines on interval

Question

I\'m using an updating spline chart to show a line that changes each second. The changing is set in chartinfo.chart.events.load. Below is the code I\'m using in my actual progra

Answer 1

In addition to series.addPoint([x, y], false, true); series2.addPoint([x, y2], true, true);

also write chart.redraw(); after series2.addPoint([x, y2], true, true); This makes it work for me in webapp

Answer 2

Set the first add point's animate parameter to false, the second add point will animate for the both of them.

series.addPoint([x, y], false, true);
series2.addPoint([x, y2], true, true);
