warn-on-insufficient-data

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.
