Contours

is an option for contour plots that specifies the contours to draw.

Details

The following settings can be given for Contours:

	n	contours at n equally spaced levels
	Automatic	contours chosen automatically
	{Automatic,n}	at most n contours chosen automatically
	{f₁,f₂,…}	contours at levels f_i
	{{f₁,gr₁},…}	contours drawn with graphics directives gr_i
	func	a function to be applied to z_min, z_max to get the list of contours

With Automatic settings, "nice" equally spaced contour levels are chosen, whose values minimize the number of digits in their decimal representation.
In ContourPlot and ListContourPlot, Contours specifies contour lines.
In ContourPlot3D and ListContourPlot3D, Contours specifies contour surfaces.
ContourPlot and ContourPlot3D let you give an equation f==g or a list of equations as a way to specify single contours to draw.

Examples
