TRSPointChartValues Methods

Add

Overloaded.  Creates a new TRSPointChartValue instance and adds it to the Items array. Call Add to create a point in the collection. The new value is placed at the end of the Items array, or, if the collection is Sorted, placed at the sorted point in the collection (based on a default value (0, 0)).

Add returns the new point value.

Note that because every time you change a value an event is called, it is faster to add and initialize a value using the overloaded Add method.
 

Add(TRSChartValueType,String,TCanvasColor,Integer)

Overloaded.  Creates a new TRSPointChartValue instance and adds it to the Items array. The new instance is initialized with the X, Caption, Color, and ImageIndex parameters. Call Add to create a point value in the collection. The new value is placed at the end of the Items array, or, if the collection is Sorted, placed at the sorted point in the collection (based on a default value (0, 0)).

Add returns the new point value.

Add(TRSChartValueType,TRSChartValueType,String,TCanvasColor,Integer)

Overloaded.  Creates a new TRSPointChartValue instance and adds it to the Items array. The new instance is initialized with the X, Y, Caption, Color, and ImageIndex parameters. Call Add to create a point in the collection. The new value is placed at the end of the Items array, or, if the collection is Sorted, placed at the sorted point in the collection (based on a default value (0, 0)).

Add returns the new point value.

CalculateMetaData

Calculates the metadata (e.g., minimums, maximums, summations, and absolute summations) for the entire values collection, for all dimensions.

The metadata is recalculated when values change and the NeedMetaData property is set to true.

FindItemID(Integer)

Returns the Item with the specified ID. The FindItemID method returns the item in the collection whose ID property is passed to it as a parameter. If no item has the specified ID, FindItemID returns nil.

GetEnumerator

Returns the enumerator for the collection, which is used when you write a "for Item in Chart.Values" loop.

Insert(Integer)

Creates a new instance and adds it to the Items array. Call Insert to add a new value at a specified position in the collection. Existing items (starting from the specified position) are moved up in the Items array. Note that Insert only works as expected if the collection is not     Sorted.

Insert returns the new collection value.
