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.

errcolor
The color to draw error bars. The default is None.
errstyle
How to draw errors. The default is None.
errthickness
What thickness of line to draw error bars. The default is None.
linecolor
What color to use for the line connecting the data points. The default is red.
linestyle
How should the line connecting the data points be drawn. The default is 1, which means a solid line is drawn.
linethickness
What thickness should be used to draw the line connecting the data points. The default is 3.
ratioline
Should a horizontal line be drawn at y=1? The default is False.
symbolcolor
What color to draw the symbol representing the data points. The default is None.
symbolfill
Should the symbol be drawn filled? The default is True.
symbolsize
What size is the symbol drawn. The default is None.
symbolstyle
What style is used for the symbols. The default is 0, which means no symbol is used.
xaxis
The default is False
xerrorbars
Should error bars be drawn for the X axis. The default is False.
xlog
Should the X axis be drawn with a logarithmic scale? The default is False. This field can also be changed with the set_xlog and set_xlinear functions.
yerrorbars
Should error bars be drawn for the Y axis. The default is False.
ylog
Should the Y axis be drawn with a logarithmic scale? The default is False. This field can also be changed with the set_ylog and set_ylinear functions.

Examples

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

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