Thanks for the extensive reply.
Actually my application will only draw one type of graphic, a dot, but it
can be thousands depending on the start en end date specified. The basic
idea is that one dot = one day. The only difference is that some dots will
be a different color. The graphic side is very very basic, so I'm
definitely not interested in general drawing.
I do not want to give away to much details here but I'm prepared to take it
"offline" if you are prepared.
