It is a commonly known issue of the current Node-RED line chart. As @hotNipi mentioned, the line chart was based on the version v2.xx of Chart.js, which is extremely inefficient. It struggles when displaying slightly fast incoming data (say more than 10 points/second).

Chart.js since 3.0 is much faster and efficient. It would be great if line chart could use Chart.js 3.0 or above.

Alternatively, thanks to @hotNipi and Christian-Me, who have provided ways to use uPlot.  
Chirstian-Me started working on a uPlot node and you can see discussions here:

> Anybody into charts (like me)? [withBands] Perhaps somebody likes to try out this one sitting on my desk too long: Still BETA so NOT on [flows.node-red.org](http://flows.node-red.org) Have fun. Any feedback highly welcome (even my time is limited so progress will not be at a fast pace) Chris

Unfortunately, there are still bugs in the node.
