TRSDonutChartExValues.Items[Integer] Property

 Scroll Prev Top Next More

Lists the donut slice values in the chart. Use Items to access individual donut slices in the collection. The value of the Index parameter corresponds to the Index property of TRSDonutChartExValue. It represents the position of the value in the collection.

The Items property is the default property for the TRSDonutChartExValues class. You can access this property with the abbreviation Values[index], which is equivalent to Values.Items[index].
 

Namespace: FMX.RS.DonutCharts

Delphi

public
  property Items[Index: Integer]: TRSDonutChartExValue read GetItem write SetItem; default;
 

Parameters

Index

Type: Integer

Property Value

Type: TRSDonutChartExValue

The following example creates a string list displaying the captions and values for all the values in the chart.

Delphi

var
   i: Integer;
   Strs: TStringList;
 begin
   Strs := TStringList.Create;
   for i := 0 to Chart1.Values.Count - 1 do
     Strs.AddObject(Chart1.Values[i].DisplayName, Chart1.Values[i]);
 end;

noteNote

Note that the AssignTo method already does this for you so this is an equivalent code block:

Delphi

var
   Strs: TStringList;
 begin
   Strs := TStringList.Create;
   Strs.Assign(Chart1.Values);
 end;
