# clabel

## Purpose

Contour plot elevation labels.

## Synopsis

    clabel(C)
    clabel(C,V)
    clabel(C,'manual')

## Description

`clabel(C)` adds height labels to the current contour plot using the contour structure `C` output from `contour`. The label positions are selected randomly.

`clabel(C,V)` labels just those contour levels given in vector `V`. The default action is to label all known contours.

`clabel(C,'manual')` places contour labels at the locations selected with a mouse. Press the Return key to terminate labeling. Use the space bar to enter contours.

## Examples

Generate, draw, and label a simple contour plot:

    [x,y] = meshgrid(-2:.2:2);
    z = x.^exp(-x.^2-y.^2);
    c = contour(x,y,z);
    clabel(c);
