Fit Manager#
Fit manager for handling curve fitting operations.
This module manages fit operations for curves, handles fit parameter storage and retrieval, and coordinates between UI and fit calculations.
- class mdaviz.fit_manager.FitData(model_name: str, fit_result: FitResult, x_range: Tuple[float, float] | None = None)[source]#
Container for fit data associated with a curve.
- class mdaviz.fit_manager.FitManager(*args: Any, **kwargs: Any)[source]#
Manages fit operations for curves.
- addFit(curveID: str, model_name: str, x_data: numpy.ndarray, y_data: numpy.ndarray, x_range: tuple[float, float] | None = None, initial_params: dict[str, float] | None = None, bounds: dict[str, tuple[float, float]] | None = None) None[source]#
Add or replace a fit for a curve.
Parameters: - curveID: ID of the curve to fit - model_name: Name of the fit model to use - x_data: X values for fitting - y_data: Y values for fitting - x_range: Optional range of x values to use for fitting - initial_params: Optional initial parameter guesses - bounds: Optional parameter bounds
Raises: - ValueError: If model_name is not available or fit fails
