The Column Chart, just like the Bar Chart, represents variation in a data series over time or compares different items. It displays values of one or more items as vertical bars against Y-axis and arranges items or categories on X-axis.

You need to set the ChartType property to Column in the Property window, in the code behind, or in XAML to create the Column Chart.

Set the Stacking property to Stacked or Stacked100pc to create the stacking WPF Column Chart.

The code below demonstrates the implementation:

<c1:C1FlexChart x:Name="flexChart" 
                BindingX="Country" 
                ItemsSource="{Binding DataContext.Data}" 
                ChartType="Column">
    <c1:C1FlexChart.Series>
        <c1:Series SeriesName="Sales" 
                   Binding="Sales"/>
        <c1:Series SeriesName="Expenses" 
                   Binding="Expenses"/>
    </c1:C1FlexChart.Series>
</c1:C1FlexChart>

flexChart.ChartType = C1.Chart.ChartType.Column;

Set Cluster Size

Similar to Bar charts, you can also adjust the space between the clusters of columns in Column charts by using the ClusterSize property of the FlexChart class. The ClusterSize property determines how much visual space the columns cluster take up on the plot area. You can set the size of clusters in terms of percentage and absolute value (i.e., in pixels) using the Percentage and Absolute enum constants, respectively. These constants belong to the ElementSizeType enumeration, which specifies the size type for the ElementSize object. You can increase the gap between the clusters by setting a lower value or decrease it by setting a higher value for the enum constants.

In the previous image, there is a noticeable gap between consecutive bar clusters. However, in the following image, the gap between the bar clusters has been reduced due to an increase in cluster size.

For setting the size of column clusters in percentage, you can use the following C# code:

flexChart.Options.ClusterSize = new C1.Chart.ElementSize() { SizeType = C1.Chart.ElementSizeType.Percentage, Value = 50};

Similarly, change the percentage to absolute to set cluster size value in pixels.
