## ZLABEL Plot Z-axis Label Function

Section: Handle-Based Graphics

### Usage

This command adds a label to the z-axis of the plot. The general syntax for its use is

      zlabel('label')

or in the alternate form

      zlabel 'label'

or simply

      zlabel label

Here `label` is a string variable. You can also specify properties for that label using the syntax

      zlabel('label',properties...)

### Example

Here is an example of a simple plot with a label on the `z`-axis.

    --> t = linspace(0,5*pi);
    --> x = cos(t);
    --> y = sin(t);
    --> z = t;
    --> plot3(x,y,z,'r-');
    --> view(3);
    --> zlabel('time');

which results in the following plot.
