footnote

Arguments: chart-or-plot

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

A string to display below a chart-or-plot's body (but above the legend if any), or else nil to avoid drawing a footnote. The string will be drawn using the footnote-color and footnote-font of the chart-or-plot. The default value is nil.

The string will be wrapped at spaces if it does not fit on one line, and space is allocated automatically to accomodate the number of lines that are required. The string may also contain embedded newline characters to explicitly wrap the text at particular places.
