Topic: PHP, Oracle and Charts

[kkiboo]

Hello all,

I'm having some trouble here: I'd like to create a series of charts based on different data sets from the same table. The problem is, most of the columns are not numeric. I have fields such as: Team, Employee, Grade, etc. Is there any good way to chart this data as in (varchar2) or do I HAVE to somehow make it numeric? If so, is there an easier way to do this via aliases perhaps? Charts are driving me mad.
