Arguments: chart-widget
Returns the value of the draw-legend property of a chart-widget. The value may be set at creation
time by passing the :draw-legend initarg, or any
time later by calling (setf draw-legend).
draw-legend indicates whether
a legend is drawn in a chart-widget. The legend is a table at the
bottom of the chart with a descriptive string for each chart object
and a visual indication of which graph line or set of bars represent
it. The chart-widget will automatically make room for the legend
whenever it is drawn.
The value may be t to draw the
legend, nil to not draw it, or
:when-multiple-objects to draw the legend if and
only if there are multiple objects in the chart-objects property. The default value is
:when-multiple-objects, since a legend is typically
needed only to differentiate multiple chart objects.
The legend will be drawn according to properties of
the chart-legend instance
that is in the chart-legend
property of the chart-widget.
