minor-tic-increment

Arguments: item-axis

Returns the value of the minor-tic-increment property of a item-axis. The value may be set at creation time by passing the minor-tic-increment initarg, or any time later by calling (setf minor-tic-increment).

The number of chart items between successive minor tic positions of an item-axis in a chart-widget. The value should be a positive integer. The default value is 1.

When the value is 1, there is a minor tic position for every chart item. This allows a tic mark and/or a tic label and/or a grid line to be drawn for every chart item. If the value were 4, then there could be a tic mark, tic label, or grid line only for every fourth chart item.
