TEXT Add Text Label to Plot

Section: Handle-Based Graphics

Usage

Adds a text label to the currently active plot. The general syntax for it is use is either 
   text(x,y,'label')

where x and y are both vectors of the same length, in which case the text 'label' is added to the current plot at each of the coordinates x(i),y(i) (using the current axis to map these to screen coordinates). The second form supplies a cell-array of strings as the second argument, and allows you to place many labels simultaneously 

   text(x,y,{'label1','label2',....})

where the number of elements in the cell array must match the size of vectors x and y. You can also specify properties for the labels via 

   handles = text(x,y,{labels},properties...)

Example

Here is an example of a few labels being added to a random plot: 
--> plot(rand(1,4))
--> text([2,3],[0.5,0.5],{'hello','there'})

Here is the same example, but with larger labels: 

--> plot(rand(1,4))
--> text([2,3],[0.5,0.5],{'hello','there'},'fontsize',20)
