Data Visualization using Perl/Tk
Idean writes "Generating a visual representation is often the best way to understand large data sets, but standard tools such as gnuplot often fall short. This article shows how to use Perl/Tk, the standard GUI toolkit for Perl, to quickly build custom plotting and graphing tools."
Examples of complicated graphs include specialized bar-and-whiskers plots
I had to cope with box-and-whisker plots to visualize data gathered from a statistical survey. Frankly, Perl/Tk was nothing I looked into (and I love Perl & Tk!). I entered the data into an OpenOffice spreadsheet (which made the statistical calculation very easy!) and googled for a solution. There are many commercial packages available for Excel, but this article was really helpful. I managed to create a similar solution for OO (I'm not sure if the result is of interest to anyone - if so, msg me or something).
Does anyone know a repository for statistical analysis programs? Because if you only need to run an analysis once, you think twice about hacking a Perl/Tk program (the 'clean' approach) unless you are a true Perl wiz - the time needed to write the program is (with my programming abilites) two or three times longer than looking for another one shot solution (the 'practical' approach).
If there was a central repository for this, you a) knew where to look first and b) had an incentive to write the program to save someone else the time. Yes, I know I could put it up to some website, but I really doubt anyone would find it or even look for it...
