High speed graphing control for .NET (or MFC)?

Question

I need to write a digital oscilloscope type application. There are many great static graphing controls out there, but I need something that can graph 16 traces processing 4

Answer 1

Check out this question. I highly recommend IOComp for both MFC (ActiveX) and .Net. Very fast and stable.

You might look at Visual Numerics.

How about ZedGraph? They mention realtime applications specifically here:

http://zedgraph.org/wiki/index.php?title=Display_Dynamic_or_Real-Time_Data

They claim at least ~20 samples per second.

At 4000 samples per second I don't think you're going to want to plot all the points in real time since you're going to make it all the way across the screen in 0.25 seconds...

Answer 4

Have you looked at GraphViz? I've seen it used in oscilloscope applications, but I'm not positive it will handle the speed you're looking for. GraphViz doesn't take a 'live feed' of instructions like some of the GDI+ controls I've seen.

There are some .NET wrappers for it.
