IAxisLabels

property Separation: Integer;

Type Library
TeeChartx

Description
Default Value: 10

The Separation property specifies the percent amount of minimum distance between Axis Labels.

Setting it to "0" zero makes Axis skip calculating overlapping labels. (No clipping is performed).

Labels visibility depends also on Labels.Font size, Labels.Angle and Axis.Increment properties.
