get_model_plot_prefs

sherpa.astro.ui.get_model_plot_prefs()

Return the preferences for plot_model.

Returns

prefs – Changing the values of this dictionary will change any new model plots. This dictionary will be empty if no plot backend is available.

Return type

dict

See also

plot_model()

Plot the model for a data set.

set_xlinear()

New plots will display a linear X axis.

set_xlog()

New plots will display a logarithmically-scaled X axis.

set_ylinear()

New plots will display a linear Y axis.

set_ylog()

New plots will display a logarithmically-scaled Y axis.

Notes

The meaning of the fields depend on the chosen plot backend. A value of None means to use the default value for that attribute, unless indicated otherwise. These preferences are used by the following commands: plot_model, plot_ratio, plot_bkg_model, and the “fit” variants, such as plot_fit, plot_fit_resid, and plot_bkg_fit.

The preferences recognized by the matplotlib backend are the same as for get_data_plot_prefs.

Examples

After these commands, any model plot will use a green line to display the model:

>>> prefs = get_model_plot_prefs()
>>> prefs['color'] = 'green'
