I need someone to build script that records at what part of the page (for long pages) the visitors left the page and display that as a heatmap.
There is a clickheat open source at [url removed, login to view] This should help. Sites like [url removed, login to view] uses it on their commercial application.
Instead of clicks, I want to track exit points. The heat map should only be applied "vertically" meaning it shouldn't track certain (X,Y) coordinate (pixel) but only (Y) coordinates.
User should be able to see the result in graphical form. as well as how many visitors came to the site.
I'm planning to integrate this features into my current php tracking script. The script should be portable as possible.
