A friend of mine is evaluating Dataviews, to create graphical user interfaces with dynamic components (ie process control and modelling). Please reply via this news group rather than email Thanks Colin Reyburn

(Real Time Advisory Control for the process control industry). The main problem with Dataviews is that it has NO IDEA of a TIMESCALE on its dynamic graphs. (1) They don't change over time, they change only when you tell them to change (2) They don't have any built in idea of historical data. Simple demonstrations looks great in off-the-shelf Dataviews, but if you want to do something more typical of a real application, like having 3 or 4 graphs on a page, say one showing X over 1 hour, one showing X over 10 minutes, and one showing X over the last 2 minutes; *then* you have a lot of work (C-programming) to do. NOTE: It was still a tremendous savings in implementation effort and time to start with Dataviews rather than starting with raw-X. -gjc
