It would be very useful if the Perspective XY Chart exposed the enabled/disabled (visible) state of each series and/or Y-axis when users toggle visibility via the chart legend.

Currently:

Users can toggle series visibility using the legend

However, there is no exposed property, binding, or event to determine which series are enabled or disabled

This state is only visible internally within the chart component

Why this is needed:

Being able to access series visibility would enable:

Dynamic Y-axis scaling based only on visible series

Conditional formatting, calculations, or data processing for enabled series only

Cleaner logic for charts with multiple Y-axes

Better UX when users interactively toggle chart data

Use case:

In multi-axis XY Charts, users may toggle individual series on/off using the legend.

The Y-axis range, formatting, and related data processing should dynamically adjust based only on currently visible series.

Without access to the visibility state, this logic must be duplicated externally or cannot be implemented at all.
