I need a control to add data trending to my application. Is anything available or do I need to use a graphing control and add my own trending features?

Trending is typically an included feature in 3rd party charting components (at least the ones i’ve seen) but it might be called something else such as linear regression or possiblly something like “least squares*.” You should definitely not need to roll your own, unless you think it would be fun. 😉
Google-ing for “Delphi Chart Regression” will turn up some interesting links.
(* Least squares is typically the method used to establish a trend line from a data set.)
