Field Value
System.Windows.DependencyProperty

IntervalValueBindingProperty

Identifies the IntervalValueBinding dependency property.

Declaration
public static readonly DependencyProperty IntervalValueBindingProperty
Field Value
System.Windows.DependencyProperty

ItemsSourceProperty

public static readonly DependencyProperty ItemsSourceProperty
Field Value
System.Windows.DependencyProperty

OrientationProperty

Identifies the Orientation dependency property.

Declaration
public static readonly DependencyProperty OrientationProperty
Field Value
System.Windows.DependencyProperty

Properties

ActualInterval

Gets the actual interval.

Declaration
public double ActualInterval { get; }
Property Value
System.Double

Interval

Gets or sets the Interval. This property defines the value length (width) of each bar in the histogram. If the property is set to null (default), an automatically interval is used. The auto-interval is calculated using the Scott's Normal Reference Rule. If the interval is bigger then the data range (max - min values), the data range is used as interval.

Declaration
public Nullable<double> Interval { get; set; }
Property Value
System.Nullable<System.Double>

IntervalValueBinding

Gets or sets the binding that will be used to get the values on the horizontal axis.

Declaration
public DataPointBinding IntervalValueBinding { get; set; }
Property Value
DataPointBinding

ItemsSource

Gets or sets the ItemsSource.

Declaration
public IEnumerable ItemsSource { get; set; }
Property Value
System.Collections.IEnumerable

Orientation

Gets or sets the orientation of the bars. The default value is Horizontal. Horizontal means that the intervals of the bars will be calculate on the horizontal axis, therefore the bars height will be relevant to the vertical axis.

Declaration
public ChartHistogramDataOrientation Orientation { get; set; }
Property Value
ChartHistogramDataOrientation

OriginValue

Gets or sets the OriginValue. This property defines the vertical origin value of the bar. The default origin value is 0.

Declaration
public double OriginValue { get; set; }
Property Value
System.Double

ValueBinding

Gets or sets the binding that will be used to get the values on the vertical axis.

Declaration
public DataPointBinding ValueBinding { get; set; }
Property Value
DataPointBinding

Methods

GetEnumerator()

Returns an enumerator that iterates through the collection.

Declaration
public IEnumerator<DataPoint> GetEnumerator()
Returns
System.Collections.Generic.IEnumerator<DataPoint>

A System.Collections.Generic.IEnumerator<> that can be used to iterate through the collection.

GetValueAggregateFunction()

When overridden in a derived class, this method returns the function used to calculate the aggregate values for the bars in the histogram.

Declaration
protected virtual ChartAggregateFunction GetValueAggregateFunction()
Returns
ChartAggregateFunction

Events

ActualIntervalChanged

Occurs when the actual interval changes.

Declaration
public event EventHandler ActualIntervalChanged
Event Type
System.EventHandler
