Charting website help

[nuno]

Good morning



I have searched the forums but unfortuanately found no answer to my question.

I would like to develop an in-house website that enables my users to graph/plot data from stored data in a mysql database. The data will be updated every evening.

Basically I would like my users to be able to select an instrument ( or two) and then the start and end dates and this would display an interactive line graph.

Does anyone know of any decent charting tools that allows users to do this?


Thanks


Nuno
