HI guys

Usually graphs are made in php using the gd library.

Here's a simple code to make a graph using gd

Here's a perl module which also uses gd.

For the second graph example..I would destroy the image at the end or will use lots of memory.

 

Place this on the last line

imagedestroy($im);

in my opinion you could be better off using a plugin such as ChartDirector

Although chartdirector is nice, it comes with a price, 750 bucks to be exact.

One year on the upgrade.

 

I have always been the type of person to go the free way instead.

yeah.

though theres an evaluation version you can mess around with.

 

another option is jpgraph. havent used it in a while but it does the trick. doesn't look as pretty as ChartDirector though
