Dear all,

I was wondering what is the chart recommand use for optimal performance on the following scenario :

  • What is the max number of point a chart can accept in a sceries of data ( my customer have nearly 10000 points to be display)
  • what is the max number of chart instance that can be visible at same time ? ( for instance user would like to see more that one chart on one screen

Thanks for those information

Hi there,

The chart can show exactly 10,250,124 points and not one more! Exactly 3.42 chart instances can be shown.

I’m joking … the actual numbers depend a lot on your hardware, the type of charts you are showing, whether updating in realtime, whether showing point-markers, whether showing linear or logarithmic axis, whether hardware acceleration is enabled, the distribution of your data etc …

This is why we advise before purchasing SciChart that you test it thoroughly for performance. You can use our examples to help you do this, for example:

  1. The WPF Chart Performance Demo shows three series totalling 10,000,000 points in real-time.
  2. This WPF Chart demo shows 50 charts shown on screen. One of our customers has 50 charts in a single application
  3. This article on WPF Chart Performance shows how data-distribution and hardware acceleration affects WPF Chart performance

If you have any specific questions then please ask, but we do advise test test test. I don’t think you will have much problem with just 10,000 points though 🙂

Best regards,
