yline
Add one or more horizontal lines in the current axes or a specified axes.
Syntax
h = yline(y)
h = yline(..., property, value, ...)
h = yline(hAxes, ...)
Inputs
- y
 - Constant point y of the horizontal line.
 - property
 - Properties that control the appearance or behavior of the graphics object.
 - value
 - Value of the properties.
 - hAxes
 - Axis handle.
 
Outputs
- h
 - Handle of the line graphics object.
 
Examples
clf;
        h = yline(2);
      
        
        Figure 1. Horizontal line at y = 2clf;
          x=[0:0.1:3*pi];
          plot(x, sin(x)); 
          h = yline([-1;1],'color','r','linestyle','--');
          ylim([-1.5 1.5])
        
        
        Figure 2. Create 2 lines and set propertiesComments
If there is no axis, one will be created first. If y is an Mx1 matrix then M horizontal lines will be created.
