Currently we offer two charting solutions for ASP.NET - RadChart and RadHtmlChart.
RadChart is our older and more mature solution. It uses GDI+ graphics to render the chart image on server and then it sends it to client (browser). The control has 17 chart series types
. Unfortunately, due its server-side nature, it does not support animations. It does not provide option to adjust the Spline rendering.
RadHtmlChart is the newer control. It is a wrapper on our KendoUI Chart, which is a client-side control based on HTML5. The client-side engine allows RadHtmlChart to provide better user experience through interactivity effects and animations. You can have a look at our online demos here
to see this yourself. Presently it does not support Spline Series.
Another option that you can consider is integrating the Silverlight RadChart in your ASP.NET page. That way you can have Spline series, animations and you can share code between the Silverlight project and the WPF one. This
blog post explains how this can be achieved.
