Arguments: chart-widget
Returns the value of the warn-on-insufficient-data property of
a chart-widget. The value
may be set at creation time by passing
the :warn-on-insufficient-data initarg, or any time
later by calling (setf
warn-on-insufficient-data).
warn-on-insufficient-data is a
boolean value indicating whether a warning is signaled when a
chart-widget does not have
adequate data for drawing itself. The default value is true.
It appears that this warning is currently signaled only if the range-top of a value-axis is not greater than its range-bottom, or if the major-tic-increment is negative.
See chart-widget and also cg-chart-widget.htm.
