subtitle

Arguments: chart-or-plot

Returns the value of the subtitle property of a chart-or-plot. The value may be set at creation time by passing the :subtitle initarg, or any time later by calling (setf subtitle).

subtitle is a string that is drawn below the main title of a chart-or-plot, typically in a smaller font (see subtitle-font). The value should be a string to display, or else nil to avoid displaying a subtitle. The default value is nil.

If the string doesn't fit onto a single line, then it is wrapped at spaces as needed, and enough space to accomodate the required number of lines is allocated automatically. The string may also contain embedded newline characters to explicitly wrap the text at particular places.

The string is drawn using the subtitle-color and subtitle-font properties of the chart-or-plot.
