YLIM Adjust Y Axis limits of plot

Section: Handle-Based Graphics

Usage

There are several ways to use ylim to adjust the Y axis limits of a plot. The various syntaxes are 
   ylim
   ylim([lo,hi])   
   ylim('auto')
   ylim('manual')
   ylim('mode')
   ylim(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 ylim('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-');
--> ylim  % what are the current limits?

ans = 
   -0.9999    0.9999

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
