## 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.
