You can also set default options as follows:
sage: var('y')
y
sage: implicit_plot.options['axes']=True # new default value
sage: implicit_plot.options['cmap']=['red'] # new default color
sage: implicit_plot(x^3+y^3-2*x*y,(x,-3,3,),(y,-3,3)) # red with axes
You can see the current defaults:
sage: implicit_plot.options
{'axes': True,
'cmap': ['red'],
'contours': (0, 0),
'fill': False,
'plot_points': 150}
and you can reset the options to the Sage defaults
sage: implicit_plot.reset()
sage: implicit_plot.options
{'contours': (0, 0), 'fill': False, 'plot_points': 150}
These options commands should work with any plotting command.
Thanks,
Jason
