value-spacing

Arguments: line-graph-view

Returns the value of the value-spacing property of a line-graph-view. The value may be set at creation time by passing the value-spacing initarg, or any time later by calling (setf value-spacing).

The minimum spacing, measured in pixels, between successive chart items on a line-graph-view in a chart-widget. The value should be a positive integer. The default value is 12.

The actual distance will be greater if needed to prevent tic labels on the item-axis from overlapping each other. See major-label-min-spacing and major-label-wrapping.

If the fit-chart-items property of the chart-widget is true, then this value will be scaled proportionally with other sizing properties to make all data fit in view.

This property is used only when the draw-lines property is true.

See also bar-spacing.
