Dynamically Created Charts/Graphs, How And What?

[phprocker]

Hey all.  I need to have dynamic charts/graphs in a project.  What's the common way these are created these days in pHp?  I've searched a bit around Google and found some pHp extensions but not sure if I should use one of them or accomplish charts/graphs with my own pHp code.

 

What's the right direction to go along these lines?

 

Thanks.

I'd say it depends on how complex you want to get.

 

It might be worth taking a look at a few of the libraries, reviewing the code and seeing if you'd like to implement it yourself.

 

PEAR Image_Graph looks like it still leaves some work for a programmer to implement it.

I may be lazy, but I use Google Charts:

I think they look great, but aren't for everything.

This is a good idea. I'd recommend this as (dynamic charts) are either creating client side code, or using an advanced GD class to generate the image data and place it on an image, which is really pointless.(And requiring a lot of memory consumtion, Let google do that for you!)

Whew - I thought I might get beat up for that

This seems like a good way to go before I write my own extensive functions.  Thanks.

If you want to practise around, here's a nice tutorial to teach you the essential basics of the PHP GD library (should be included on default PHP installations) and includes the tutorial as a bar char, ironically.
