In addition to the standard text that is displayed, titles, footnotes, and axis labels have alternate short text. If there is not enough space to display the standard text, then the short text is displayed. For example, if you resize a graph and there is not enough space to display the whole axis label, then the short axis label is displayed. If you later enlarge the graph so that enough space is made available, then the long label is displayed.

This behavior is supported as long as you do not make any change to the text of the title, footnote, or axis label. Once you change the text, then only the new modified text is displayed regardless of the size of the graph.
