You can use our Annotations (Custom GridLine
) to achieve your scenario. For example if you want to have an Average line which should cross the average point in your data, you should find this average point in your data. If your datasource is a List for example or any generic you may use a LINQ Aggregator
function to find the average amongst your elements.
Also as a side note - I would like to ask you to post your future questions in their corresponding Product forum. Since your question is related to RadChart for WPF - I suggest that we continue our further comunication on this there or in a new formal Support thread.
All the best,
the Telerik team
