Statistics/transformation accessor for any xr.Dataset. Access via dataset.fxstats.

Provides data transformation methods that return new datasets. Chain with .plotly for visualization.

Values are sorted in descending order along the 'time' dimension. The time coordinate is replaced with duration (percentage or index).

Returns:
