Description

**Describe the solution you'd like**

**Additional context**
As sometimes values can be deceiving or missing, I like it when my graphs show to which direction are my axis increasing value.

Research direction

Start by locating the LineChart implementation and its current axis-rendering path. Determine how an opt-in arrow setting should cover the X and Y axes, then verify the rendered result matches the requested examples while preserving the default appearance.
