Yup, similar experience here. And graphing calculators have now been promoted to the point where their importance is probably no longer questioned ... which is too bad ...
There are many ways to graph python-generated computer data. I have dabbled with many, but for various reasons I continue to use the best one I've ever found: NPLOT. If you haven't heard of NPLOT it would not surprise me. NPLOT is a Fermilab product, developed about 12 year ago. It is written in C. It is a beautiful thing and allows interactive, dynamic exploration of multi-column (aka "ntuple") data in many different representations. You can download nplot from ftp://ftp.fnal.gov. It only runs on Linux. If you are a teacher using Linux and Python then you might very well love what NPLOT can do. At the heart of it are some very powerful graphing widgets. Your python program just needs to write tab-separated columns of data and NPLOT will read it no problem. If anyone tries this and needs help, feel free to contact me ... I've used this product extensively for years. Lots of sample code I could provide. Anyway, Python + Nplot = GreatAlternativeToGraphingCalculator. -Charles 2009/9/28 Brian Blais <bbl...@bryant.edu> > On Sep 27, 2009, at 19:38 , Charles Cossé wrote: > > Hi, this has probably been discussed to death already, but maybe not: The > point at which fancy graphing calculators become "necessary" (ie as in one's > student career) is the point at which the calculator should be abandoned and > Python employed.
