Because of the large number of possible algorithms, we don't provide built in computation for trend lines. Our focus is instead on making sure that a user can display trend lines that they've calculated, along with the right amount of interactivity support. We have a very basic demo of this functionality in the cookbook: Oracle JET - Chart - Custom Charts: Trendline. In this demo, we recommend using reference objects, rather than additional series, because the reference objects don't allow a user to interact with individual points or use features like selection or drilling, all of which would be undesirable for a trend line.
On the second question, could you provide more details on what slider you're referring to? We have two different ways to use our zoom and scroll functionality:
- Overview Window: Oracle JET - Chart - Zoom & Scroll: Time Axis
- Simple Scrollbar: Oracle JET - Chart - Zoom & Scroll: Categorical Axis
Thanks for the quick response.
I saw the zoom and scroll feature in action and expecting that should fit the UI expectations in our application.
