Hi guys,

Related with my previous question: how do I add the anottation lines to the chart legend? It seems it only gives me options about the data series, nothing else…

Hi Jose,

It isn’t possible to do this natively, however the LegendControl is just an ItemsControl with DataTemplate that binds to a collection of SeriesInfo objects provided by LegendModifier, so should be easy to create a custom legend.

Take a look at the hierarchy of the LegendControl with a visual debugger, e.g. WPF Snoop. Also check out SeriesInfo in the API documentation so you can see the available properties.

Also take a look at this thread which talks about custom legends and includes the ControlTemplate for the LegendControl.

Hope this helps!
