ASP.Net 4 Charting from SQL Database

I already have some graphs being created using GDI from a sql database. They are very basic and I would like them to be much more professional looking. The graphs will be based in some stored procedures from a sql database and are very simple.

Along the X axis will either be :-

Monthly Report: 1 tick for each week in chosen month
Quarterly Report: 1 tick per week per month for period chosen
6 monthly: 1 tick per month for period chosen
Yearly: 1 tick per month for period chosen

The Y axis will be from 0 to the maximum value but the Y axis will effectively start at a negative value so that even 0 values will show a bar height

The user must have the ability to choose either a bar or line chart and each chart must have a target line ( or shading ). Any entries above that target would be coloured green and any below red. The use may also decide to show 1, 2,3 or 4 charts per page.

Each chart will be shown for the period chosen and for a chosen product. there may be up to 20 products.

The charts must be compatible with IE, Chrome and Firefox

I have attached examples of the current charts ( or at least similar to what tey look like )
