Terminal TdxChartXYSeriesValueLabels Class Descendants

Do not use the TdxChartXYSeriesValueLabels class directly. Use the following descendants instead:

TdxChartXYSeriesBarValueLabels: Stores value label appearance and behavior settings for an XY series with an active Bar View.
TdxChartXYSeriesLineValueLabels: Stores value label appearance and behavior settings for an XY series with an active Line or Area View.

The ValueLabels property of an XY series View references one of these classes as a TdxChartXYSeriesValueLabels object depending on the actual series View type.
