When I used scichart real-time graph for 3 days(no stop), It does not draw smoothly.

It looks broken… draw, wait for 1 second, draw, wait…..(repeat)

but first day, It worked well..

Why is it??

I use buffer size(1843200) and draw 80 fast lines.

and Memory in my PC is 16GB.

Please help me to solve this problem….

    We will need code to reproduce this. Also I would suggest updating to latest version of SciChart via Nightly Build (v5.1.1) as this has solved some important memory leaks. Doing some performance + memory profiling can help as well.

My guess based in information provided would be that there is memory fragmentation or a memory leak in your application.

This memory leak could be because of your code, or SciChart code, however, note there are no reported memory leaks as of the latest version of SciChart (v5.1.1.11505)

I would suggest updating to the latest nightly build ( to see if the problem still exists. Instructions on updating can be found here.

If the problem still occurs, please can you provide code to reproduce the problem. We will gladly investigate.

Best regards,
