real-time plotting program suggestions

By heytrent at Thu, Apr 3 2008 2:20pm |

My team is in need of a cross platform real-time plotting tool, does anyone have suggestion?

Fundamentally, we just want a "scope" on our simulation to see how it's behaving. We can put the data out over a tcp/ip port or in any form the program dictates. I just can't seem to find any open source (free) tools that offer this. We'll post process and generate formal plots using matplotlib or matlab so what we need for real-time doesn't have be fancy.

Any suggestions would be appreciated.

I was thinking doing

I was thinking doing something similar using http://code.google.com/apis/chart/ let us know how things go. You might want to combine that with some PHP and have some sort of webserver.

Best regards

hi-

http://www.vvidget.org/builder/description/websignal.html

is not cross platform, but you can use it to plot signals from a http type source (TCP/IP directed through HTTP), a web service source. It is free.

http://www.vvi.com/products/daq/plot.html

has a network source model, but only for very sophisticated realtime custom TCP/IP network sources (sophisticated == expensive (sorry), realtime upto something like 100k/sec or greater). Or, the USB hardware is realtime (upto 50K/sec), but needs analog signals.

http://www.vvidget.org/service

is free, but not realtime (the way we define it) over the Internet. But if you are EDU you can setup a free one on your LAN/WAN and it performs pretty darn well. And, you can export to a post processing layout tool (free).

thanks!-
