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."

Re:Perl or Line Noise

And how did your control group do?

What language was Perl compared to using this methodology?

Did the test subjects have experience with Perl? And, what of the control group?

Perl is different, no doubt about it. But, it doesn't *have* to look like line noise.

"and I don't see how Perl could help, as numerical processing is certainly not its strength!"

Have you explored PDL (piddle)? I find it to be a very powerful way to manipulated datasets.

If you're a good programmer, you can read the line noise.

At the same time, a good perl hack wouldn't write unreadable code. I often rewrite a complex operation, breaking it into 3 or 4 step, out of courtesy to the poor schmuck who has to maintain the code.
