Hi Oliver,

Each series has a LegendItemVisibility property.  It's just a matter of hooking up this property to the view model like the series binder does with a number of other series properties.  I added a property for legend visibility so now you can tell it what property in your view model you want to use for controlling whether it is visible in the legend or not and the series binder will bind the Series.LegendItemVisibility to it.
