You might be able to get something to work with the XY chart following a gnatt style. You might need to do a little scripting to get the data in the correct format, and then run that at a set rate (once every 5s?) I don't think you'll be able to get a smooth scroll effect with built in components.
If you are allowed to add modules, consider adding pturmel's Integration Toolkit.(Free) It adds functions to allow iteration in an expression. This would allow you to build the data for this xy chart entirely in an expression.
