Creating and writing Graphs to File

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

Hi, I am new to perl but have managed to create a script to gather performance stats from the Unix box I am working on. The script outputs the information to a comma seperated file so the output is like: Time,IO/s,CPU....... 10:20:15,100.95,87.3....... I want to produce a script to generate a results doc which will take the figures from the file and produce graphs such as CPU over Time and IO/s over Time, however I do not know where to begin. Any advice would be helpful. I see there is a CPAN module which could help but all documentation says to install 'Some::Module' but all I know is that the module is called GD. Cheers, Tom

Hi, Some GD docs GD.pm or the GD::Graph FAQ or the GD::Graph::Map site I have whacked a simple piece of code together for this type of thing. I am outputting the GD stuff to a PNG file and then displaying this in a web page. This script is purely a sample it displays GD::Graph as well as GD::Graph::Map which allows you to click on the bar and output a further query that is run in from the `@urls` script not show here.

I think the module you're meaning is GD::Graph. This seems to be able to do what you need, according to its docs, though I haven't used it so can't say for sure. Info about installing modules is on CPAN. Hope that helps some .. -- Foxcub	[reply]

GD::Graph is really nice. You will need to install GD as well. I recommend you install the latest version (2.06 as of the date of this node) which requires `libgd` version 2.0.5 or higher (which you can get at http://www.boutell.com/gd/) jeffa L-LL-L--L-LL-L--L-LL-L-- -R--R-RR-R--R-RR-R--R-RR B--B--B--B--B--B--B--B-- H---H---H---H---H---H--- (the triplet paradiddle with high-hat)	[reply]
