How do you plot text in MatLab?

To add text to one point, specify x and y as scalars. To add text to multiple points, specify x and y as vectors with equal length. text( x , y , z , txt ) positions the text in 3-D coordinates. text(___, Name,Value ) specifies Text object properties using one or more name-value pairs.

How do I align the text in an annotation text box?

First, by default, the alignment of the text in an annotation text box is in the upper right corner. That positioning is done before the box is trimmed to the text, which leaves the text floating pretty far from the desired location. You can change this easily by adjusting the vertical alignment.
