We're integrating WPF charts at the moment and was wondering how to go about specifying a custom label for a data point.
For example, we have an IEnumerable of complex data items which are being plotted. We are using the YPath/XPath approach to read properties from each component. Each point on a specific series has a special meaning which should be labelled, so that when we mouseover it, the description appears. The label needs to come from a property on the data point instance, which is neither the X nor the Y value.
I'm probably missing something very obvious, and any pointers would be greatfully accepted.
