hi Bryan, unfortunately you're not able to post your code, (btw why not ?) but maybe you can answer a few questions .... Bryan Cole wrote:
Hi,
I'm an ex-LabView user, now using python for lab data-acquisition and analysis for some years now. It's well worth the switch.
I'm too a former MatLab / LabView user, and I'm quit happy with Python / Scipy / wxPython for now. At the moment I'm trying to write an open source LabView equivalent, first results can be seen here: http://oase.uci.kun.nl/~mientki/data_www/pylab_works/pw_animations_screensho...
Your best bet is http://pyqwt.sourceforge.net/
You're right, matplotlib/chaco are too slow for "interactive real-time" type work. The strengths of these packages are their presentation-quality output (vector and anti-aliased bitmap graphics).
For data-acquisition applications, I prefer wxPython to Qt (I may move to something based on Traits/ETS once I figure out how to install it). For GUIs I have a home-made plotting widget which is fast enough for real-time work. Unfortunately, I'm not yet in a position to post it publicly. If you need *really* high performance, it's not too hard to write a plot-widget using PyOpenGL directly.
I'm in the middle of writing a real time plot widget, based on direct canvas drawing, don't know yet how fast it is. I hope to make a video of it next week. But I wonder if you've a good data-acquisition module. I've one now (can use Soundcard , some NI-modules and several dedicated DAQ cards), but it's in fact a windows executable that I can control from Python. And of course I', looking for a more OS-indepedant solution. cheers, Stef
