DataPointCollection Class

Namespace:
GemBox.Spreadsheet.Charts
Assembly:
GemBox.Spreadsheet.dll

Represents a collection of chart series data points.

public sealed class DataPointCollection : IEnumerable<DataPoint>, IEnumerable
Public NotInheritable Class DataPointCollection
    Implements IEnumerable(Of DataPoint), IEnumerable
Inheritance:
System.Object
DataPointCollection
Implements
System.Collections.Generic.IEnumerable<DataPoint>
System.Collections.IEnumerable

Properties

Count

Gets the number of elements contained in the DataPointCollection.

public int Count { get; }
Public ReadOnly Property Count As Integer
Property Value
System.Int32

The number of elements contained in the DataPointCollection.

Remarks

Retrieving the value of this property is expensive, so cache it instead of retrieving it multiple times.

Item[Int32]

Gets the data point at the specified index.

public DataPoint this[int index] { get; }
Public ReadOnly Property Item(index As Integer) As DataPoint
Parameters
index
System.Int32

The zero-based index of the data point to get.

Property Value
DataPoint

The data point at the specified index.

Remarks

If you are iteratively indexing all data points, it is preferable to use the DataPointCollection enumerator in a langword_csharp_foreach statement instead because each indexer call validates the index by using the Count property whose retrieval is expensive.

Methods

GetEnumerator()

Returns an enumerator that iterates through data points.

public IEnumerator<DataPoint> GetEnumerator()
Public Function GetEnumerator As IEnumerator(Of DataPoint)
Returns
System.Collections.Generic.IEnumerator<DataPoint>

An System.Collections.Generic.IEnumerator<T> that can be used to iterate through data points.
