minor-tic-length

Arguments: chart-axis

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

The length, measured in pixels, of minor tic marks on a chart-axis of a chart-widget. The value should be a non-negative number. The default value is 3.

Minor tic marks are drawn only when this property and minor-tic-width are positive numbers and the draw-minor-tics property of the chart-axis is true.
