[vtk-developers] Parallel coordinates chart looking nice

Hey Marcus,

It looks like you're making some good progress on this, and I see that it shows up as a view in ParaView now, too!

I don't want to be bugging you about it, but it looks like so far the AnnotationLink stuff is built in so that outside links will be reflected in the parallel coordinates chart, but selections made within the parallel coordinates chart do not update the internal annotation link selection list (and do not fire AnnotationChangedEvent). Is this something that you plan to add soon? (Or, am I misreading the code as it stands?)

Again, I don't want to be bugging you, but I am curious whether I should spend time trying to plug this into my personal copy since I need it for my own use, or if you'll be addressing it soon in the main repository? 

Thanks again,
