The X and Y-axis captions may be formatted with a simple picture format such as:

chSet 'cpic' 'XXXXXX;'

To force the captions to wrap at the length of the given string. If the string is simply ‘XXXXXXX’ then longer captions are truncated, and end with ‘...’ to indicate this.

This only applies to X-captions and Y-captions set with style ‘AtEnd’. Vertical Y-captions are not multiline.
