Live ECG plot in WPF

Question

What would be the best (easy and fast) approach to plot live ECG data in a WPF application? I am thinking about writing my own control that would use paths to visualize the signal. But maybe there are ready to use graph libraries that suite my need? Do you have any experience in that area?

Answer 1

I know that Visifire has live updating and a line graph-- I'm not sure if it's fast enough for your needs, though. But it is free until you sell something and opensource.

Answer 2

You might be able to use Dynamic Data Display. Its very flexible and performance beats all of the commercial products I have tried.

Answer 3

Thanks for all your answers, however all third party components using retained graphics mode were too slow. I've decided to use WritableBitmap with double buffering and unsafe code and an Image control.
