contour_fit_resid

Context: visualization

Synopsis

Contour the fit and the residuals to a data set.

Syntax

contour_fit_resid(id=None, replot=False, overcontour=False, **kwargs)

Description

Overplot the model - including any PSF - on the data. In a separate plot contour the residuals. The preferences are the same as `contour_data` and `contour_model` .


Example

Plot the fit and residuals for the default data set:

>>> contour_fit_resid()

PARAMETERS

The parameters for this function are:

Parameter Type information Definition
id int, str, or None, optional The data set that provides the data and model. If not given then the default identifier is used, as returned by `get_default_id` .
replot bool, optional Set to True to use the values calculated by the last call to `contour_fit_resid` . The default is False .
overcontour bool, optional If True then add the data to an existing plot, otherwise create a new contour plot. The default is False .

Bugs

See the bugs pages on the Sherpa website for an up-to-date listing of known bugs.
