Add
|
Overloaded. Creates a new FMX.RS.Charts.TRS3DChartValue instance and adds it to the Items array. Call Add to create a 3D 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, 0)).
Add returns the new 3D 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)
|
Overloaded. Creates a new FMX.RS.Charts.TRS3DChartValue instance and adds it to the Items array. The new instance is initialized with the X, Caption, and Color parameters. Call Add to create a 3D 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, 0)).
Add returns the new 3D value.
|
|
Add(TRSChartValueType,TRSChartValueType,String,TCanvasColor)
|
Overloaded. Creates a new FMX.RS.Charts.TRS3DChartValue instance and adds it to the Items array. The new instance is initialized with the X, Y, Caption, and Color parameters. Call Add to create a 3D 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, 0)).
Add returns the new 3D value.
|
|
Add(TRSChartValueType,TRSChartValueType,TRSChartValueType,String,TCanvasColor)
|
Overloaded. Creates a new FMX.RS.Charts.TRS3DChartValue instance and adds it to the Items array. The new instance is initialized with the X, Y, Z, Caption, and Color parameters. Call Add to create a 3D 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, 0)).
Add returns the new 3D value.
|
|
Add(TRSChartValueType[],String,TCanvasColor)
|
Overloaded. Creates a new TRSChartValue instance and adds it to the Items array. The new instance is initialized with the Values, Caption, and Color parameters. Call Add to create a 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)).
Add returns the new value.
|
|
Append(TRSChartValues)
|
Appends the Source values to the current collection (Inherited from FMX.RS.ChartPanel.TRSChartValues.)
|
|
Assign(TPersistent)
|
Represents method Assign(TPersistent). (Inherited from FMX.RS.ChartPanel.TRSChartValues.)
|
|

Represents method AssignTo(TPersistent). (Inherited from FMX.RS.ChartPanel.TRSChartValues.)
|
|
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.
|
|
Clone
|
Creates a copy of the values collection. This is a "deep" copy, e.g., all items and their properties are copied. The new collection is returned. The Owner of the collection is the same as the current collection's Owner . Note, you are responsible for freeing the clone. (Inherited from FMX.RS.ChartPanel.TRSChartValues.)
|
|
CustomSort(TValuesSortCompare)
|
Sorts the current values collection using the supplied comparison function. Use CustomSort when you want to perform a special type of sorting on the values collection. You need to define a function based on the FMX.RS.ChartPanel.TValuesSortCompare signature.
If you want to do normal sorting, just call the Sort method.
|
|
FindClosest(TRSChartValueType)
|
Returns the Index of the Item that is closest to the Value parameter. FindClosest uses the Values in the sorted dimension ( SortByDimension) to determine the nearest value. If the collection is not sorted, this function returns -1. (Inherited from FMX.RS.ChartPanel.TRSChartValues.)
|
|
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.
|
|
GetAbsSum(Integer)
|
Represents method GetAbsSum(Integer). (Inherited from FMX.RS.ChartPanel.TRSChartValues.)
|
|
GetAxisMaximum(Integer)
|
Returns the maximum value in the collection for the specified dimension. (Inherited from FMX.RS.ChartPanel.TRSChartValues.)
|
|
GetAxisMinimum(Integer)
|
Returns the minimum value in the collection for the specified dimension. (Inherited from FMX.RS.ChartPanel.TRSChartValues.)
|
|
GetEnumerator
|
Returns the enumerator for the collection, which is used when you write a "for Item in Chart.Values" loop.
|
|
GetIsDateTime
|
Represents method GetIsDateTime. (Inherited from FMX.RS.ChartPanel.TRSChartValues.)
|
|
GetMaxValue(Integer)
|
Represents method GetMaxValue(Integer). (Inherited from FMX.RS.ChartPanel.TRSChartValues.)
|
|
GetMinValue(Integer)
|
Represents method GetMinValue(Integer). (Inherited from FMX.RS.ChartPanel.TRSChartValues.)
|
|
GetSortByDimension
|
Represents method GetSortByDimension. (Inherited from FMX.RS.ChartPanel.TRSChartValues.)
|
|
GetSum(Integer)
|
Represents method GetSum(Integer). (Inherited from FMX.RS.ChartPanel.TRSChartValues.)
|
|
GetValueDimMaximum(TRSChartValue,Integer)
|
Returns the maximum value for the dimension. This may be modified by other values. For example, the shape value modifies the X value by adding the width value. This method is called by the CalculateMetaData method.
Notes to Inheritors
|
Override this method if you need to return a maximum value for a dimension that is depends on other factors than just the value in TRSChartValue.Values[Dimension]. For example, the TRSCandleStickChartValues class overrides this method for the Y dimension because the Y dimension is bounded by the High Dimension and Low Dimension, not the Close value.
You will probably also need to override the SetMetaData method to set the new maximum.
|
|
|
GetValueDimMinimum(TRSChartValue,Integer)
|
Returns the minimum value for the dimension. This may be modified by other values. For example, the shape value modifies the X value by adding the width value. This method is called by the CalculateMetaData method.
Notes to Inheritors
|
Override this method if you need to return a minimum value for a dimension that is depends on other factors than just the value in TRSChartValue.Values[Dimension]. For example, the TRSCandleStickChartValues class overrides this method for the Y dimension because the Y dimension is bounded by the High Dimension and Low Dimension, not the Close value.
You will probably also need to override the SetMetaData method to set the new minimum.
|
|
|
IndexOf(TRSChartValueType,Integer)
|
Returns the Index of the Item that contains the Value parameter (or close to the Value parameter) for the specifed Dimension. If the Collection is sorted by the specified Dimension, IndexOf calls the FindClosest method. However, if the collection is not sorted or not sorted by the specified Dimension, the method iterates through the collection looking for a value that is approximately equal to the specified Value. (Inherited from FMX.RS.ChartPanel.TRSChartValues.)
|
|
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.
|
|
Loaded

|
Notify(Classes,Classes)

|
|

|
|
SetMetaData(TValueMetaData,TRSChartValue,Integer)
|
Sets the metadata (min, max, sum, etc) by using the TRSChartValue.Values property. The Dimension parameter specifies the dimension to use in the Values property. This method is called by the CalculateMetaData method when it finds a value "better" than the current metadata value (e.g., less than current minimum)
|
|
Sort
