Examples

This example demonstrates how to create a histogram chart.

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

<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"
                                                     GridLayoutMode="GridAndLabelCentered"
                                                     Pattern="{}{OB}{A1:F0}; {A2:F0}{CB}"
                                                     OverflowValuePattern="{}{OS} {A1:F0}"
                                                     UnderflowValuePattern="{}{US} {A2:F0}"/>
                    <!--...-->                                                                  
                </dxc:AxisX2D.NumericScaleOptions>
                <dxc:AxisX2D.WholeRange>
                    <dxc:Range SideMarginsValue="0.8"/>
                </dxc:AxisX2D.WholeRange>
                <dxc:AxisX2D.Title>
                    <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:BarSideBySideSeries2D>
    </dxc:XYDiagram2D>
</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.
