title: Draw a column graph with no space between columns
body: <p>I am using the WPF toolkit, and am trying to render a graph that looks like a histogram. In particular, I want each column to be right up against each other column. There should be no gaps between columns.</p>
  
  <p>There are a number of components that you apply when creating a column graph. (See example XAML below). Does anybody know if there is a property you can set on one of the elements which refers to the width of the white space between columns?</p>
  
  <pre><code>                &lt;charting:Chart Height="600" Width="Auto" HorizontalAlignment="Stretch" Name="MyChart"
                      Title="Column Graph" LegendTitle="Legend"&gt;
  
                      &lt;charting:ColumnSeries 
                          Name="theColumnSeries"
                          Title="Series A"
                          IndependentValueBinding="{Binding Path=Name}"                
                          DependentValueBinding="{Binding Path=Population}"
                          Margin="0"
                          &gt;
                      &lt;/charting:ColumnSeries&gt;
  
                      &lt;charting:Chart.Axes&gt;
                          &lt;charting:LinearAxis 
                              Orientation="Y" 
                              Minimum="200000" 
                              Maximum="2500000" 
                              ShowGridLines="True" /&gt;
                          &lt;charting:CategoryAxis
                              Name="chartCategoryAxis"
                              /&gt;
                      &lt;/charting:Chart.Axes&gt;
                  &lt;/charting:Chart&gt;
