Contour Plots

The contour functions create, display, and label isolines determined by one or more matrices.

Contour Plotting Commands

Function	Description
clabel	Generates labels using the contour matrix and displays the labels in the current figure.
contour	Displays 2-D isolines generated from values given by a matrix Z.
contour3	Displays 3-D isolines generated from values given by a matrix Z.
contourf	Displays a 2-D contour plot and fills the area between the isolines with a solid color.
contourc	Low-level function to calculate the contour matrix used by the other contour functions.

Two other functions also create contours. meshc displays a contour in addition to a mesh, and surfc displays a contour in addition to a surface.
