Spline Series

The spline series are similar to the line series but instead of straight line segments, the spline series connects its data points with a smooth curve which represents rough approximations of the missing data points. Here is an example of a chart with a spline series:

CopyXAML
<chart:RadCartesianChart x:Name="chart">
   <chart:RadCartesianChart.HorizontalAxis>
      <chart:CategoricalAxis/>
   </chart:RadCartesianChart.HorizontalAxis>

   <chart:RadCartesianChart.VerticalAxis>
      <chart:LinearAxis/>
   </chart:RadCartesianChart.VerticalAxis>

   <chart:SplineSeries Stroke="Orange">
       <chart:SplineSeries.DataPoints>
           <chartEngine:CategoricalDataPoint Value="20"/>
           <chartEngine:CategoricalDataPoint Value="40"/>
           <chartEngine:CategoricalDataPoint Value="35"/>
           <chartEngine:CategoricalDataPoint Value="40"/>
           <chartEngine:CategoricalDataPoint Value="30"/>
           <chartEngine:CategoricalDataPoint Value="50"/>
       </chart:SplineSeries.DataPoints>
   </chart:SplineSeries>
</chart:RadCartesianChart>
