value-axis

Arguments: chart-widget

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

value-axis is an axis of a chart-widget that indicates the magnitude of the displayed data values. This property value is an instance of the value-axis class, and holds properties that determine how the axis is drawn and the range of values that it displays.

The value of this property is always a value-axis instance. If you do not pass a value-axis instance as the value of the :value-axis initarg when creating a chart-widget, then a default instance is created automatically.

If there are multiple chart objects (see chart-objects), then some of the objects may use this value axis while others use the secondary value axis that is in the value-axis-2 property.

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