a percent bar

senik148 has asked for the wisdom of the Perl Monks concerning the following question:

Hello Perl Monks.

in perl is there modules. or existing code. to enter a percentage for example: 80% and bring a graphic bar showing that percentage. like the ones used for cPanels and stuff.

||||||||||||||||| 70% complete

and that bar will have color etc. it has to show the full bar + color percentage of 70% use of the bar.
but my big problem was i have a list of projects for example:

project xml: 40% project html: 70% project flash: 15% project video: 6%

how can i convert all that into a summary percentage. i.e.
Full project: 45% completed

my brain hurts! help!

In what context do you wish to render this percentage bar? A browser? A dialog box on a specific operating system? A dialog box in a cross-platform solution? A terminal? Under Tk, you have a lot of options: Tk::ProgressSplash, Tk::ProgressBar, Tk::ActivityBar, to name a few. Under Curses, you have Curses::UI::Dialog::Progress. Under browsers, you have CGI::ProgressBar, under Gtk2 you have Gtk2::CV::Progress. There's Term::Progress too. All those options can be found by visiting http://search.cpan.org and typing in the word, "`progress`". Dave	[reply] [d/l]

A great starting place would be chancellor tachyon's wget style progress bar. An LWP implementation thereof is described at http://hacks.oreilly.com/pub/h/943, and may help you to understand how to use it in context. 0xbeef	[reply]
Re: a percent bar by negation (Beadle) on Dec 29, 2005 at 08:36 UTC
A very simple way to calculate the overall percentage is just to sum percentages of projects and divide the result by amount of projects. In your case it would be: (40% + 70% + 15% + 6%) / 4 = 32.75% That assumes that you consider each project to be equal in size or amount of required work. If that is not the case, you could add appropriate weights to project percentages before summing them up. I hope that helps.	[reply]
