Web Programmers will love this one!!! Not only this one is free, flashy but it is also OPEN SOURCE!!! (My Personal Favourite Criteria For Any Software/Codes)
Why choose Open Flash Chart?
This is a little gentle propaganda for the project. Like all opinions, disregard it and make up your own mind.
Edge cases such as
tooltips encourage user interactivity and data exploration
The CakePHP manual is quite clear about the fact that images, style sheets and javascript files should commonly be put into respectively webroot/img, webroot/css and webroot/js. However, it is not clear for someone who is new to CakePHP what is the general rule for giving the correct path to these ressources. Routinely the designer who has to work with CakePHP may wonder why using routes, static pages and controller/actions do not yeld the same results as to path correctness.
While testing the framework, the newbie is suggested that helpers be used to correctly output some familiar HTML tags. One then comes to transform all tags into $html->image() method calls. But what about background images ? and what about type="image" inputs ?
Using the webroot property in the html helper
After trying the various CakePHP global constants (ROOT, WEBROOT_DIR, WWW_ROOT, CSS, etc.) with no results, the general solution seems to be found in the $this->webroot property that returns the path to the application webroot. Thus for the various cases above we may have in our layouts, views or elements:
A simple image tag: echo $this->webroot; ?>img/foo.gif" .../ >
A background image within a table cell the old way: echo $this->webroot; ?>img/foo.gif">
A background image within a table cell, the styled way (illustrating external CSS case as well): echo $this->webroot; ?>img/foo.gif) }">
An input of type="image": echo $this->webroot; ?>img/go_btn.gif" ... />
Coding consistently
For consistency's sake, one may even use exclusively this property for all paths and links inside the application. Instead of replacing img tags everywhere while leaving backgrounds and image inputs with a different syntax (applies also to CSS paths, Javascript paths and links), one may bypass the use of some of the helper methods altogether (such as $html->css(), $javascript->link()) and use only the sole webroot helper property.
