I am using a tooltip template in Rad Cartesian Chart View for ScatterSplineSeries. I defined Point Template and tooltip template and able to display X & Y Values. I want to Display the Horizontal Axis Title along with X value and Vertical Axis Title with Y Value. Also I would like to display the spline name too. Somehow I am not able to display the contents. I read in telreik about DataItem property of DataPoint class and even tried using it but unsuccessful .Here is my XAML and View Model.
