major-tic-length

Arguments: chart-axis

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

The length, measured in pixels, of major tic marks on a chart-axis in a chart-widget. The value should be a non-negative integer. The default value is 6.

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