Legends with check boxes

I would like to create a ChartController for a plot with multiple series. The ChartController would contain items similar to a legend but with a checkbox next to each series. The checkbox would allow the user to toggle the visibility of the series. How should I implement this? How can I display a short segment of the line in a listbox?

(I edited the title to make it easier to search in the discussion threads)

Check boxes and list boxes are not supported by the OxyPlot core - you need to define these in an overlay.
This should be included in the examples, I have created an issue:
