TcxGridChartController.FirstVisibleCategoryIndex Property

Specifies the index of the first visible category in a paged diagram.

Declaration

property FirstVisibleCategoryIndex: Integer read; write;

Property Value

Type	Description
Integer	The index of the first visible category in a paged diagram.

Remarks

The specified category will become either the first visible category or will simply be scrolled into a View. In the latter instance, the FirstVisibleCategoryIndex property will return the index of the first visible category.

The result of specifying this property depends upon the following settings:

• The total number of categories in the View (ViewData.VisibleCategoryCount).

• The number of categories displayed at a given time in a paged diagram (OptionsView.CategoriesPerPage).

• The order used to display categories in a diagram (AxisCategory.CategoriesInReverseOrder).

After the first visible category has been changed, the View’s OnFirstVisibleCategoryIndex event occurs.
