We need to replicate the attached excel in a PHP environment. The tasks consists in:
- Creating the inputs to do calculations (in excel) and graph them.
- Each input needs to be saved in a specific Product (record).
- Each data entry needs to be saved in a history to at leats 30 past entries (to be displayed).
If you can incorporate this into a CMS like joomla/worpress is a PLUS.
See excel and formulas for more info.
