get_fit_plot
(id=None)¶ Return the data used to create the fit plot.
Parameters: id (int or str, optional) – The data set that provides the data. If not given then the default identifier is used, as returned by get_default_id. Returns: data – An object representing the data used to create the plot by plot_fit. It contains the data from get_data_plot and get_model_plot in the dataplot
andmodelplot
attributes.Return type: a sherpa.plot.FitPlot instance See also
get_data_plot_prefs()
- Return the preferences for plot_data.
get_model_plot_prefs()
- Return the preferences for plot_model.
get_default_id()
- Return the default data set identifier.
plot_data()
- Plot the data values.
plot_model()
- Plot the model for a data set.
Examples
Create the data needed to create the “fit plot” for the default data set and display it:
>>> fplot = get_fit_plot() >>> print(fplot)
Return the plot data for data set 2, and then use it to create a plot:
>>> f2 = get_fit_plot(2) >>> f2.plot()
The fit plot consists of a combination of a data plot and a model plot, which are captured in the dataplot and modelplot attributes of the return value. These can be used to display the plots individually, such as:
>>> f2.dataplot.plot() >>> f2.modelplot.plot()
or, to combine the two:
>>> f2.dataplot.plot() >>> f2.modelplot.overplot()
