          <chart:SfChart.SecondaryAxis>
              <chart:NumericalAxis/>
          </chart:SfChart.SecondaryAxis>

    }​
}​

public class LineSegmentExt : LineSegment
{​
    public override UIElement CreateVisual(Size size)
    {​
        // Write your customization code here.
    }​

    public override void Update(IChartTransformer transformer)
    {​
        // Write your customization code here.
    }​
}
