Returns

prefs – Changing the values of this dictionary will change any new contour plots.

Return type

dict

contour_model()

Contour the values of the model, including any PSF.

Notes

The meaning of the fields depend on the chosen plot backend. A value of None (or not set) means to use the default value for that attribute, unless indicated otherwise.

alpha

The transparency value used to draw the contours, where 0 is fully transparent and 1 is fully opaque.

colors

The colors to draw the contours.

linewidths

What thickness of line to draw the contours.

xlog

Should the X axis be drawn with a logarithmic scale? The default is False.

ylog

Should the Y axis be drawn with a logarithmic scale? The default is False.

Examples

Change the contours for the model to be drawn in ‘orange’:

>>> prefs = get_model_contour_prefs()
>>> prefs['color'] = 'orange'
>>> contour_data()
>>> contour_model(overcontour=True)
