Unfortunately, the RadChartView does not expose SplineRange series. You need to know that you can submit a feature request in our feedback portal
. Please remember that you need to provide us with sufficient information about the user scenario that such series will be useful and why no other series can achieve it.
Regarding the referenced feedback item, please remember that the best way to be notified when an item from our portal changes its status is to follow it. By doing so you will be notified with an e-mail. There is no need to regularly ask about any progress. We will change the status of the item when we start implementing it and once more when we implement it.
Thank you for understanding.
