Entry points

Contour.contourFunction
contour(x, y, z, level::Number)
contour(x, y, z, level::Number, VT::Type)

Trace a single contour level, indicated by the argument level. The extracted vertex type maybe be specified by VT.

You'll usually call lines on the output of contour, and then iterate over the result.

Contour.contoursFunction

contours returns a set of isolines.

You'll usually call levels on the output of contours.

Accessors

Contour.levelFunction

level(c) Indicates the z-value at which the contour level c was traced.

Contour.linesFunction

lines(c) Extracts an iterable collection of isolines from a contour level. Use coordinates to get the coordinates of a line.

Contour.coordinatesFunction

coordinates(c) Returns the coordinates of the vertices of the contour line as a tuple of lists.

Utilities

Contour.contourlevelsFunction

contourlevels(z,n) Examines the values of z and chooses n evenly spaced levels to trace.
