title: Customize sparrow toolkit axis label
body: <p>I like customize axis label style in sparrow toolkit. i wrate this code:</p>
  
  <pre><code>&lt;sparrow:SparrowChart.XAxis&gt;
      &lt;sparrow:CategoryXAxis Interval="1"&gt;
          &lt;sparrow:CategoryXAxis.LabelTemplate&gt;
              &lt;DataTemplate&gt;
                  &lt;TextBlock Text="V" FontSize="12"/&gt;
              &lt;/DataTemplate&gt;
          &lt;/sparrow:CategoryXAxis.LabelTemplate&gt;
      &lt;/sparrow:CategoryXAxis&gt;
  &lt;/sparrow:SparrowChart.XAxis&gt;
  </code></pre>
  
  <p>i like replace static string "V" with X property value of Model object that i use to build the collection of points. i don't understand how to set DataSource and how to build it.</p>
  
  <p>if i don't define DataTemplate, at run time i have the right X value, but i need change the color.</p>
  
  <p>I hope someone can help me.</p>
