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

XAML

xaml

<dxc:ChartControl x:Name="chartControl">
    <dxc:XYDiagram2D>
        <dxc:XYDiagram2D.AxisX>
            <dxc:AxisX2D TickmarksMinorVisible="False" 
                         GridLinesVisible="True">
                <dxc:AxisX2D.NumericScaleOptions>
                    <!-- Configure a histogram chart with the specified number of bins. -->
                    <dxc:CountIntervalNumericScaleOptions AggregateFunction="Histogram" 
                                                          Count="5" 
                                                          GridLayoutMode="GridAndLabelShifted"/>

                                    BarWidth="1">
        </dxc:BarSideBySideSeries2D>
    </dxc:XYDiagram2D>
</dxc:ChartControl>
