How to add a new point without redraw?
How to update a existed point without redraw?
Maybe I should ask how to update or add the existed data points, make it looks like without redraw?
I just need draw two data points,but the jqChart('update') redraw all other data points.

Currently you need to redraw (with jqChart('update') ) the chart when you change the data. What's the issue when redraw? jqChart is quite fast and redrawing shouldn't be an issue.

I understand. Currently the chart doesn't support transition animations and you need to use the chart "update" method.

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.
