invert-axis

Arguments: chart-axis

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

A boolean value indicating whether the values of a chart-axis in a chart-widget should increase in the atypical direction. The default value is nil.

The "typical" direction is defined as from bottom to top for a vertical axis or from left to right in a horizontal axis. The values of an axis whose invert-axis property is true will increase in the opposite direction. For an item-axis, this property affects the direction in which new chart items are added.

Either the value-axis or the item-axis of a chart-widget may be the vertical or the horizontal one as well; see chart-orientation.

See chart-widget and also cg-chart-widget.htm.
