TdxChartSecondaryAxisXCollectionItem Class
A secondary axis of arguments in a collection of X-axes.
Declaration
TdxChartSecondaryAxisXCollectionItem = class(
TdxChartCustomSecondaryAxisCollectionItem

A secondary axis of arguments allows you to complement the main axis of arguments (X-axis) with a different scale. For example, a secondary axis can be useful if you need to display multiple measurement units simultaneously.
Note
The TdxChartSecondaryAxisXCollectionItem class is a wrapper for the TdxChartSecondaryAxisX class that implements the functionality of a secondary axis of arguments.
