How to do 'cursor sync' on multiple time series plots, based on time?

I just made the switch from C# based trading platform to Matlab for the 'machine learning' tools and ease of integration.. One big part that's missing (at least to a novice like me) is, say I have a 5min price data, and a 15m price data (of the same symbol), how to do 2 plots (one each), and have a cursor synced on the time on these two plot windows?
