By default the

AspectRatio is 1:

Use an

Automatic setting to get the natural ratio:

Draw both

and

axes:

Use a black boundary around the edges of the surface:

Use a red boundary around the edges of the surface:

Use a thick red boundary around the edges of the surface:

BoundaryStyle does not apply to cuts made by

Exclusions:

Show clipped regions like the rest of the surface:

Leave clipped regions empty:

Use pink to fill the clipped regions:

Use light red where the surface is clipped above and pink below:

Color by scaled

coordinate:

Named color gradients color in the

direction:

Make everything red above a contour at

:

Color with blue if contour values are negative, with red otherwise:

Add labels to contour lines:

Label with values in frames:

Use 10 equally spaced contours:

Use automatic contour selection:

Use at most 5 automatically selected contours:

Use specific contours:

Use specific contours with specific styles:

Use a function to generate a set of contours:

Have contours at the 10% and 90% percentile values:

The automatic shading is darker at low values and lighter at high values:

Use

None to only show the contour lines:

Shade between contours using a color function:

Use an explicit list of colors between contours:

The default contour style is a partially transparent line:

Use black contour lines:

Use

None to not show contour lines:

Alternate between red and dashed contour lines:

Use dashed red contour lines:

Use different styles for different equations:

Use dashed red lines for all the equations:

Show where

ContourPlot samples a function:

Count how many times

is evaluated:

This uses automatic methods to compute exclusions:

Indicate that no exclusions should be computed:

Give exclusions as an equation:

Give multiple exclusion sets:

Use a condition with the exclusion equation:

Use both automatically computed and explicit exclusions:

Use a red line to indicate the exclusion set:

Omit excluded points:

Draw no frame:

Draw frames on the bottom and the left edges only:

Use the independent variables as frame labels:

Refine the surface where it changes quickly:

Show the initial and final sampling meshes:

Use 5 mesh levels in each direction:

Use mesh lines in the

and

directions:

Use mesh levels corresponding to fixed distances from the origin:

Use red mesh lines:

Use red mesh lines in the

direction and thick mesh lines in the

direction:

Generate a higher-quality plot:

Emphasize performance, possibly at the cost of quality:

Use more initial points to get smoother contours:

Automatically compute the

range:

Use all points to compute the range:

Show the surface over the full

,

range:

Automatically compute the

,

range:

Use an explicit

range to emphasize features:

Plot over an annulus region in

and

:

Regions do not have to be connected:

Use any logical combination of conditions:

Limit an elliptic curve to the unit disk:

Evaluate functions using machine-precision arithmetic:

Evaluate functions using arbitrary-precision arithmetic:
