Morris bar charts with AJAX (Laravel)

Ajax-Instructions.md

Did I hear you wanted AJAX charts instead of hard coded? You got it.

Follow this guide to integrate bar chart reports into your Laravel application with AJAX. Reports like the following come with this guide:

• Total number of Orders by day
• Total number of Users subscribed by day
• etc

The library used for the charts is: http://www.oesmith.co.uk/morris.js/

The source for a full route/controller/view is attached. Enjoy!

This link gets a 404. I believe the new link may be this: http://morrisjs.github.io/morris.js/
