Interface IChartData

Represents strongly typed Chart datapoints collection.

Inherited Members

System.IDisposable.Dispose()

Namespace: Syncfusion.Windows.Chart

Assembly: Syncfusion.Chart.Wpf.dll

Syntax

public interface IChartData : INotifyCollectionChanged, IDisposable

Remarks

Interface defines methods and properties that are required for proper chart building.

Examples

This sample demonstrates how interface can be implemented: C#:

class CustomPoint : IChartDataPoint
{
public CustomPoint(double X, double Y)
{
this.X = X;
this.Y = Y;
this.Values = new double[] {Y};
}
public double X {get; set;}
public double Y {get; set;}
public double[] Values {get; set;}
public bool IsEmpty {get; set;}
public bool Visible {get; set;}
public ChartSegment ParentSegment {get; set;}
public object Item {get; set;}
public object Clone()
{
CustomPoint customPoint = new CustomPoint(this.X, this.Y);
//...
// Filling proper fields.
//...
return customPoint;
}
}
// Custom collection strongly typed as CustomPoint that implements IChartData.
class CustomChartPointsCollection : ObservableCollection <CustomPoint>,
IChartData
{
public new IChartDataPoint this[int index]
{
get { return base[index]; }
}
public ChartValueType XValueType { get; set; }
}
//Using classes
//...
//Creating a new chart1 with area and series.
//...
CustomChartPointsCollection customCollection = new
CustomChartPointsCollection();
customCollection.Add(new CustomPoint(1, 3));
customCollection.Add(new CustomPoint(2, 5));
customCollection.Add(new CustomPoint(3, 2));
customCollection.Add(new CustomPoint(4, 8));
chart1.Areas[0].Series[0].Data = customCollection;
