I really like how this sample behaves, new series can be added to the chart without the need to redraw all the other series.

http://www.jqchart.com/j...rt/RealTime/ChartSeries

Unfortunately when I try to replicate this functionality in my application the chart always redraws itself when you call the $('#jqChart').jqChart('update'); function.

All the other series that are already on the chart are redrawn as well which is no good. Any one have any ideas why this might be happening?

Thanks,
Alex.

Hi,

Currently jqChart redraws all the series, but the redrawing is really fast.

What is the issue in your sample when all the series are updated?

Actually it's ok, I had animation turned on so the chart was reanimating each time update was called. Disabling animation makes it redraw much faster.

I have been struggling with this redraw for a month now. We have a requirement of drawing 200k points and every second there is a addition of 5 points as received from a realtime data source. This chart is being drawn and we observe a lag when the page contains multiple of the charts and it spikes the chrome memory footprint and CPU.
We are using jquery-3.6.0 jquery.jqChart-4.1.0 libraries.

A sample code for the same is posted in this forum.
