major-label-min-spacing

Arguments: item-axis

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

The minimum distance, measured in pixels, that is maintained between the labels at major tic positions of an item-axis in a chart-widget. The value should be a non-negative integer, or else nil for no minimum. The default value is 8.

When the value is a number, the distance between major tic positions will be large enough that there is at least that much space between successive major tic labels.
