hi... i successfully used fusioncharts to generate data from my table in MySQL.... now i wish to do the same to one of my php pages... which can calculate which item/drug is A class, B class and C class (based on demand and sales, A are the highest demand drugs).... however i dont save the result in my database... its just for viewing purposes... so what i want to do is... to generate a chart based on this table, for example drug name and what is the percentage of demand.... i attached a printscreen of my table below... thanks in advance...
