Improve documentation for all Functions in Charts

Customers (e.g., TotalEnergies) have requested better documentation for the Functions available in Charts.
Today, many function descriptions in Charts itself are very minimal, and users struggle to understand:

• what each function actually does

• the underlying formula or method

• when the function should be used in real analysis

They would like clearer explanations, formulas and simple usage guidance.

Charts uses Cognite’s Industrial Data Science Library (INDSL), but the current documentation is hard to find from within Charts.

Request: Provide more complete, user friendly documentation for all Functions in Charts, ideally including formula + short “when to use it” guidance (one example of a solution).
