I have several graphs that I want to keep in sync when paning and zooming. For that I use the XAxisrangeChanged, but (as jsytniak also had a problem with in http://forums.ni.com/ni/board/message?board.id=232&thread.id=3022&view=by_date_ascending&page=1), it is not smooth at all. While paning in graph1, graph2 updates very quickly but my main graph (graph1) is very much slower. Any suggestion? Can I control how often XAxisRangeChanged is called to make it slower but smoother?
