get_fit_contour

sherpa.ui.get_fit_contour(id: IdType | None = None, recalc: bool = True, copy: bool = True) → sherpa.plot.FitContour

Return the data used by contour_fit.

Changed in version 4.19.0: The contour object is now copied by default. To get the previous behaviour set the copy attribute to False.

Parameters:

idint, str, or None, optional

The data set. If not given then the default identifier is used, as returned by get_default_id.

recalcbool, optional

If False then the results from the last call to contour_fit (or get_fit_contour) are returned, otherwise the data is re-generated.

copybool, optional

Is the contour object copied before being returned? If so then the contour attributes will not be changed by multiple calls to this routine.

Returns:

fit_dataa sherpa.plot.FitContour instance

An object representing the data used to create the plot by contour_fit. It contains the data from get_data_contour and get_model_contour in the datacontour and modelcontour attributes.

Raises:

sherpa.utils.err.DataErr

If the data set is not 2D.

sherpa.utils.err.IdentifierErr

If the data set does not exist or a source expression has not been set.
