## ZLIM Adjust Z Axis limits of plot

Section: Handle-Based Graphics

### Usage

There are several ways to use`zlim`

to adjust the Z axis limits of
a plot. The various syntaxes are
zlim zlim([lo,hi]) zlim('auto') zlim('manual') zlim('mode') zlim(handle,...)

The first form (without arguments), returns a 2-vector containing the
current limits. The second form sets the limits on the plot to `[lo,hi]`

.
The third and fourth form set the mode for the limit to `auto`

and `manual`

respectively. In `auto`

mode, FreeMat chooses the range for the axis
automatically. The `zlim('mode')`

form returns the current mode for the axis
(either `'auto'`

or `'manual'`

). Finally, you can specify the handle of an
axis to manipulate instead of using the current one.

### Example

--> x = linspace(-1,1); --> y = sin(2*pi*x); --> plot(x,y,'r-'); --> zlim % what are the current limits? ans = -0.5000 0.5000

which results in

Next, we zoom in on the plot using the `zlim`

function

--> plot(x,y,'r-') --> zlim([-0.2,0.2])

which results in
