All fields can have different types of data whereas a single field should have some type of data. Why are Suriname, Belize, and Guinea-Bissau classified as "Small Island Developing States"? Please see above. '', Run MATLAB Functions in Thread-Based Environment, Modern Slavery Act Transparency Statement. I just realized why I was having so much trouble - in MATLAB you can't store strings of different lengths as an array using square brackets. Modifiers remain in effect until the end of the text. format | int2str | num2str | sprintf | fprintf | formattedDisplayText. For example, text([0 1],[0 1],{'first','second'}). So, I had to opt for string-method to put the additional information on the plot. For a list of properties, see Text Properties.
