YLIM Adjust Y Limits of plot

Usage

There are several ways to use ylim to adjust the y limits of a plot. The x-axis retains its current limits. The four syntaxes are

   ylim([lo,hi])   
   ylim(lo,hi)
   ylim('auto')
   ylim auto

where in the first two forms, the new y-limits on the plot are [lo,hi]. In the second two forms, the axes limits are automatically selected by FreeMat.

Example

Here is an example of using ylim to zoom in on the y axis of a plot without changing the x limits. First, the plot with default limits

--> x = linspace(-1,1);
--> y = sin(2*pi*x);
--> plot(x,y,'r-');

which results in

Next, we zoom in on the plot using the ylim function

--> plot(x,y,'r-')
--> ylim(-0.2,0.2)

which results in
