Example

This example demonstrates how to create a histogram chart.

The code below configures a histogram for a chart with a numeric x-axis scale.

XAML

<dxc:ChartControl x:Name="chartControl">
    <dxc:XYDiagram2D>
        <dxc:XYDiagram2D.AxisX>
            <dxc:AxisX2D TickmarksMinorVisible="False" 
                         GridLinesVisible="True">
                <dxc:AxisX2D.NumericScaleOptions>
                    <!-- Configure a histogram with the specified number of bins. -->
                    <dxc:IntervalNumericScaleOptions AggregateFunction="Histogram"
                                                     OverflowValue="20"
                                                     UnderflowValue="-30"

                                                     Pattern="{}{OB}{A1:F0}; {A2:F0}{CB}"

                    <dxc:AxisTitle Content="Temperature (°C)" FontSize="14" Margin="0" Padding="0"/>
                </dxc:AxisX2D.Title>
            </dxc:AxisX2D>
        </dxc:XYDiagram2D.AxisX>
        <dxc:BarSideBySideSeries2D  DisplayName="Temperature" 
                                    DataSource="{Binding}" 
                                    ArgumentDataMember="Temperature" 
                                    BarWidth="1">

</dxc:ChartControl>

The following API members configure the histogram options:

Member	Description
`IntervalNumericScaleOptions`	The options that provide means to create axis intervals whose number and width are calculated automatically.
ManualNumericScaleOptions.AggregateFunction	Gets or sets the function that is used to aggregate numeric axis data when one of the AxisX2D.NumericScaleOptions, AxisX3D.NumericScaleOptions, or CircularAxisX2D.NumericScaleOptions properties is set to ManualNumericScaleOptions.
WidthIntervalNumericScaleOptions.Width	Gets or sets the interval width in x-axis measurement units.
IntervalNumericScaleOptions.OverflowValue	Gets or sets the start value for the interval that includes overflow values.
IntervalNumericScaleOptions.UnderflowValue	Gets or sets the end value for the interval that includes underflow values.
IntervalNumericScaleOptions.GridLayoutMode	Gets or sets the value that specifies the alignment of grid lines, major tickmarks and axis labels.
IntervalNumericScaleOptions.Pattern	Gets or sets a format string that configures text for the interval axis labels and crosshair labels.
IntervalNumericScaleOptions.OverflowValuePattern	Gets or sets a format string that configures text for the overflow interval axis labels and crosshair labels.
IntervalNumericScaleOptions.UnderflowValuePattern	Gets or sets a format string that configures text for the underflow interval axis labels and crosshair labels.
